No it does not harm the gnutella network because gnucleus and morpheus
both provide their own ultrapeers to support the load. It is true the
version of gnutella in gnucleus is not up to date, but it does not harm
the network for the reason above. The gnutella2 implementation took
time to do, but it was well worth it. We are in the process now of
updating the gnutella protocol to be more compatible with limewire and
bearshare clients.
