Discussion is already up on the MLdonkey Lists about possible infringement of the MLDonkey GPL License.
MLdonkey connects to all kinds of Networks, as Edonkey, Overnet , Bittorrent , Gnutella, Gnutella2 and Fasttrack and that seems where the Morpheus NEOWhateverTech (insert your favourite marketing-droid-speak here) code comes from.
BTW, apart from being GPL and from being written for linux originally, MLdonkey gives you a nifty web-interface which lets you search and download (at home) all sorts of stuff while hanging out at the office
