Re: [Sipping] P2P why not multicast DNS for discovery?

[Marshall Eubanks <marshall.eubanks at gmail.com>]

There has been discuss of a native support of application layer
multicast (also known as automatic tunneling, where the multicast
would fall back to unicast tunneling if not supporting) which has been
languishing because of a lack of a killer app. This is very close to
decentralized P2P, but its synchronous and would have router support.
The current version of this is AMT - here is a draft
