This remark on source-mobility agnostics of Bi-Dir PIM we already
started to discuss in MOBOPTS, cf.
http://tools.ietf.org/html/draft-irtf-mobopts-mmcastv6-ps ... and we
started keeping an eye on it a while ago: it's really interesting!

And yes, we are looking at this and are interested in working a way
further down there ...

For the moment I personally doubt, though, that Bi-Dir can easily be
extended to scale beyond domains.

Anyway, Bi-Dir PIM can at least be embedded in (mobility-agnostic)
hybrid approaches, cf.
http://samrg.org/about/meetings/ietf69/mw69-foilsV2.pdf

Cheers,

thomas
