Unfortunately, I can't reproduce the cold boot tuning problem now. We'll
send syslog information if our partner universities report the similar
issue. Sorry.

currently, though we're working on a commercial implementation of the
RTP profile.
If you're interested in the GPL'ed UDP profile code, we can email it to
