I used this some time ago to help me identify some of my "other" traffic,
which presently amounts to ~58% of my outbound and ~50% of my inbound
traffic.  A significant amount appeared to be Gnutella-related (port
6346, in particular), but ports 8888 and 6699 also showed up, which
I'm fairly certain (especially 6699) are Napster.  Do, or can, the
current Napster rules reflect traffic related to client pushes, rather
than just pulls??  In addition to the other percentages, flowscan
identifies 39% of my outbound traffic as Napster.
