	Yep. If you want to watch the whole network, that's exactly how
you do it. Incidentally, connecting to lots of Ultrapeers will also do
wonders for your query reach, but then you'll need a lot of Ultrapeers
to hold all the leaves that will connect to multiple Ultrapeers:

Hello,

	In [1], the last paragraph of section 4.1 on page 7, they mention
similar odd behavior (highly connected leaves, non-responsive, and don't
forward queries).  Their footnote suggests that these nodes may be related
to the RIAA lawsuits, or some marketing campaign to watch consumer behavior.

hi,Daniel Stutzbach
	I measured the gnutella network recently, I find that some leaves
have large degree more than 1000, according the rfc of gnutella, which says
that one leaf need only connect to 2 or 4 ultra peers, so I wonder what
kinds of peer that have such a large number of ultra-peer parents? are they
really existing or just come testing nodes?
