Hi Alex,

For measurements, see:

The system described in this paper is now built into sfront, we have
a SIP server running at Berkeley that a few people have used since
we released sfront networking last week, things seem to be working OK;
actually a new sfront release that fixes some problems on poorly-
configured DHCP clients will be coming out later today. To read how
this sort of networking runs on sfront, see:
http://www.cs.berkeley.edu/~lazzaro/sa/sfman/user/network/index.html
Hope this helps, the approach sfront uses is IETF-based (RTP + SIP),
a different approach is to use Open Sound Control, hopefully people
doing OSC work will post as well ...

LAD seems pretty broad-based topic-wise, I'd think its OK ... also,
though, you might want to joing this, very-low-volume list:
