<< Kazaa is the original, Morpheus is Kazaa with a name change. >>
Ahh no, Morpheus is the KaZaa engine with some changes to the interface and backend.
It was developed that way so the Kazaa people could liscense their version of p2p to other companies.
So you might very well see Kazaa and Morpheus (and any other programs based on the same tech), work
in different ways. The cool thing is they all connect to the same data, so Morpheus users still share
with Kazza user and others.
