Lately I find myself wondering if there's not room for a uniform layer 2.5

more passive waiting for ARP requests), there would be an explicit L2.5
multicast join/leave (no more sniffing for L3 multicast requests) [...]
(has this already been worked on and I just don't know about it?)
See also http://www.ietf.org/internet-drafts/draft-perlman-zerouter-rbridge-00.txt It doesn't address authenticating link access.
I think that the idea of Dave Thaler's draft, though (and similar work by others) is to switch at layer 3, so that there is no need for layer 2 switching in this type of environment.
Right.
And also to providing bridging of IP traffic across link layers that don't use 48bit 802-style L2 addressing.
