Excellent - I hadn't found this reference - it looks like exactly what I
am after.

Thanks to everyone on the list for answering my questions and sending
references.

BTW, if anyone is interested in further discussions about SIP and Chord
towards possibly writing a paper or I-D on the topic, feel free to email
me off-list.  There is a lot of interest in this topic right now in the
VoIP/SIP world that could use some input from Chord/DHT experts.

Thanks,
