Hello,
First thing: I did learn some French at school, but that was two decades ago. I might completely misunderstand everything here. It might even be that this whole thing is an April's fool that went wrong (in regards to the calendar, that is). Just a few random thoughts from my side follow anyway.

Le projet "J'ai l'inux" vise à proposer une distribution Linux capable de filter les contenus notamment pornographiques, pour une utilisation à l'école.
If I understand this correctly, you want to filter out pornographic material at school, and the target is to create a linux distribution for this application.
Pour filtrer les contenus, il est nécessaire d'intervenir à l'intérieur du système pour intercepter les contenus à filtrer (on ne peut pas intervenir au niveau des trames réseau car à ce niveau les contenus ne sont pas interpétables).
If I understand this correctly, you thing you can only do this on the system itself, because you think it's not possible to intervene at the network layer. Well, actually, it is. If you connect your systems to the internet via a firewall, you can block everything you want. You can also install a transparent proxy, and your proxy may well be able to filter content. You could use junkbuster for this.
J'ai pensé à utiliser des machines virtuelles pour déléguer à chaque machine virtuelle une portion spécifique du système à assurer.
Of course you can use virtual machines for what you want to achieve, but it seems unnecessary here.
Cette idée est née d'un poisson d'avril (April's fool joke) qui annonçait le projet Canterbury, visant à réunir le meilleur de 5 distributions Linux dans une nouvelle distribution.
So your idea is born from an April's fool joke, but in the end, it looks like one itself.
En tant que chrétien, je suis très sensible aux poissons d'avril qui ont pour objectif de se moquer des chrétiens.
For this sentence, I needed google's translate in order to possibly make sense of it, but then I quite don't. "As a Christian, I am very sensitive to April's fool jokes which aim to make fun of Christians." Well, as a Christian I don't see how this "5 Linux distributions now become one in the Canterbury project" aims to make fun of Christians. Furthermore, there are quite a few possible explainations on how the "April's fool jokes" emerged, but none of the ones I know particularly targets at Christians. You might to choose to explain this sentence again (in English) so that I might have a chance to really understand what you wanted to say.
J'ai donc choisi ces 5 distributions et j'ai fait un prototype de test 64 bits:
- Archlinux pour l'interface homme-machine et la virtualisation
- Gentoo pour la compilation
- Grml pour les entrées-sorties
- Open-Suse pour les applications
- Debian pour les applications 32 bits et la modélisation
So you use 5 distributions in order to do 5 different jobs in one single project. I believe this is an April's fool joke just because it seems so stupid to select 5 different methods of administrating your systems (all those distributions use their own toolset for configuration, apart from Grml and Debian, as Grml is built on top of Debian) just in order to use all of them in one single project.
L'idée sous-jacente à ce projet, c'est un module noyau à développer qui permettra de router les appels système vers chaque distribution en fonction du type d'appel système et du rôle de chaque distribution dans le système.
If I understand this correctly, you want to route systems calls to each distribution dependend on the role of the distribution in your project. Somehow, that doesn't make any sense to me.
Le pattern MVCA (Modèle= données, Vue=ihm, Controleur=noyau, Action=application) est utilisé entre Archlinux, Grml et OpenSuse.
Le filtrage de contenu s'effectue entre les applications et les vues grâce au module noyau qui intercepte les données à filtrer et les dirige vers un filtreur hors noyau. Le filtreur applique des outils sur les données pour décider si elles seront autorisées ou non.
Seems you also want to create a kernel module to decide what to intercept when. I don't see how this should be necessary.
Pour développer le filtreur, un nouveau langage, Pmal, est à créer. On a besoin d'un nouveau langage qui doit être capable de faire évoluer ses programmes sans avoir à les interrompre. Ce langage sera basé sur du typage fort, pour assurer la sécurité du système. J'ai imaginé un langage de glue pour faire ça.
For the filter, you seem to want to create a new language (which you call Pmal) that should be able to intercept what a program does without actually disturbing the program. Sounds like "let's reinvent something like strace, but add the possibility to change the system calls' return values on the fly". That's actually something every virtualisation does in some way or another, but not for filtering content, but for intercepting and filtering hardware access. I still think it's better to use junkbuster and friends.
[language specification ideas deleted]
De plus, bien que fortement typé, ce langage pourra être exécuté par du javascript,
If you want to run a language in javascript, you usually aim at running the stuff on the browser end. You should be aware, however, that at the browser end, the USER is in control and can modify your stuff however HE sees fit, especially circumventing any blocking or filtering that happens on that level.
In the end of the day, I still think I didn't understand what you really want to achieve (no wonder, as I didn't use French in 20 years), but if I understood any of your intentions correctly, I just would think twice if there isn't an easier way to achieve your goals.
Bye,
Thomas
