Shareaza is -ware free and source code is available: http://shareaza.sourceforge.net/
It downloads from bitorrent, gnutella, and edonkey all from one app.
Yes, P2P programs themselves don't break the law, but sharing copyrighted material without permission does break the law, in basically all countries on Earth.
