Bill,

Thanks for the response. I've gotten about 10 responses or so from various
parties. There seems to be various opinions, and the two most popular being
DNS Service Discovery and WS-Discovery. SSDP also seems fairly lightweight
to implement, since it is a part of UPnP spec.

We hope to make a decision over the next few weeks, and start implementing
in Q1 of 2013.
