Well, I've been on-line for 48 hours now. I'm still running in Client mode, and I've only uploaded a handful of files. Basically, I'm wasting money on unused bandwidth. I've been handed-off from Ultrapeer to Ultrapeer (at least 5 that I've noticed), some of whom report "0 hosts". So, I would have to say that the Ultrapeer technology needs some more tuning!

When I run Bearshare and maintain 4 connections, my upload bandwidth is max'd, my upload slots are full (15), and I'm turning away people. With Limewire 2.0-beta, I've never had more than 3 uploads and I'm only averaging 1 upload.

The specific problems I've observed:
- servents with high-bandwidth and high uptime are not being promoted to Ultrapeer
- servents that are operating in Ultrapeer-mode are not reporting many hosts or forwarding many requests, i.e. they don't seem to be well-connected servents
- Ultrapeers should report the size of their horizon, rather than their hosts/connections
- servents with less than 4 connections should not be promoted to Ultrapeers
