Salut Morgwen! Morpheus is an mozaïc of other people engines: GnuDNA (and not Jtella wich was for V2 of Morpheus) for gnutella and G2, Mldonkey for Fasttrack and Overnet and work of a USA university for Neo. Kayaman and Ewok
(I don't remember his nickname) have posted in the Gnucleus.com forum about their work in Morpheus and all and yes XoloX is indeed dead. Kayaman even told people to go to the gnuDNA forums if Morpheus has bugs with gnutella and G2 implementations (I doubt they code anything, they maybe pay chinese people to do the interface, who knows???
).
Ciao
