I heard LimeWire is working on a (CC) verifier for their
filesharing program.

Filesharing programs that are (CC)-Aware are essential,
because with the latest RIAA lawsuits it'll be a relief to
be able to search for mp3s marked OK for filesharing.

It'll be nice for me, i'm an avid filesharer (until the RIAA
mass-threat of lawsuits. now i hide out on IRC sharing
only cartoons.) and the first program which comes out
with such a feature will probably get a usership boost.

Now if only KaZaA and ShareAza could start work
in that area...
