I have a friend that was working on reverse engineering the Morpheus protocol...
it seems that a group of people are working on making an opensource morpheus client but he has quit the project and he doesn't know where it stands, but he said that when he left there were few things to bee discovered yet (he made a great deal of discoveries when he joined the group).
We should be expecting a client any time now...but expect it first on linux, then wait for a Darwin (or even MacOS X) port...
