Well, what I have always thought is that gnutella programs should include encoding abilities for music possibly video, that way the same song isn't encoded in a thousand different ways (diferent bitrates, sizes,) or at least sponsor or at least suggest a decent encoder that most users can use.

And at the very least it should have either a naming utility (not seperate) or suggest a standard for naming files like citation standards in literature.

These things would ensure that more files of the same song coincide, No?
