Remap Controller

[eluser]xwero[/eluser]
I did this week something similar. I made a pages module where users add their own pages and the titles are converted to urls.

The solution i used is add the language to the url and check if the page name exists in the database using the language from the url as a limiter.

Using a language file is a bit more difficult because it's a static file and the language class is instantiated after the router class.

You could try to use a pre controller hook to process the urls.
