First, congrats!  I think the CWN idea has languished in a lot of ways,
primarily because the larger geek community doesn't think much about
media, content and organizing.  Its great to see UC bringing all of
those things to bear.

Not sure if you've seen this but Apple has an Open Source zeroconf mDNS
advertiser.  Check out mDNSResponder at:


In DC we use it for the wireless network in the building where our
office is to advertise our media server.  This, in conjunction with
daapd, makes it appear automatically in iTunes for people.

I think the daemon is probably the easy part.  Much harder will be
getting applications to use the services and deploying those
applications to end users, iTunes and iChat are the only apps I'm aware
of that use them.  I've heard that iChat uses the Jabber protocol when
its in local/mDNS mode, I think it would be great if yall funded Jabber
client development in this vein.

I'd love what your plans are for apps in this area, as that's where all
of this will ultimately get interesting.  I vote for a VOIP gateway
advertisement mechanism.
