I was looking for a free (possibly open source) provider of automatic translations for my open source application I am working on and quite had troubles finding some. Then I realized we have a project called "wiktionary" which could possibly (I was assuming it's open dictionary) help me here, but I was quite disappointed as I couldn't find any simple way to perform simple queries like:

translate "banana" from english to czech

I think that we could (maybe should in spirit of openness and wikiness) have some wiki-based web application that would serve this purpose - allow people query / translate simple words, but maybe even whole phrases. If anyone could edit this, maybe it would grow up into huge dictionary of all possible or frequent phrases that could be easily translated to any language on world.

Do we already have anything like this?
