Ultrapeer seems to reduce message passing and likely drops bad 0.4 connections. Leaf clients (modem users) pass messages only when they search or positively respond to a search. I believe the ultrapeer the leaf clients connect to keeps a file list for them (?) and so they may only get upload requests.
