... you'd need some preprocessing first. The ASCII characters `0' and `1' aren't easy to use to write a program, though you could do it with nasm and some '-' and '+'s I suppose.

If someone can prove me wrong, I'd be very happy though. Writing a program using just '0' and '1' (the ASCII characters) would be awesome. (in an established programming language, and no homomorphisms. :) )
