I can imagine it really being a very open project with outside contributors, but I'm not sure that the exact same tools will work with other languages.<p>For example, I think that dealing with something like Python would require a completely different set of translations because it is mainly dictionary based.<p>That's not to say that doing an X to C++ converter isn't possible or a good idea, I just think that the HipHop techniques may not apply to other languages very easily.
