I really like the idea of a smart, portable build system that doesn't have more dependencies than the target project.
Edit: Even thought I may not be "invited", I have to say, a mix of C/C++ seems the way to go if only because you'll lose some talent if you stick to either language exclusively.
I don't care that much what the project is (still think MVC style editor = silly), but I'm with phantomotop here and would very much like to see a mix of C and C++. I don't know C++ but almost certainly intend to learn it, just not now/not for this. Since this is my first collaborative experience, I'd like to see what gets done how and with what, and I will be using C.
