Page content localisation

I'm really considering using GitIt for our community wiki, but one down side is the lack of functions to localise the content to many languages.

Our intention is to create something like wikipedia does, where each page can have versions on other languages even if the page names are different.

For now there's no need to translate the interface, but the content would be perfect.

I was thinking that each page could have some metadata about their language, or maybe each language's pages be saved into a folder with their 2 digit codes.

To connect the pages between them a metadata with the location of the other "translated" pages could be into each page, or this info be stored on another file.

Links to the same article on different languages would be shown just like Wikipedia.

I hope this is not a nightmare to create.
