Harsh was asking about multicast support for wireless nodes.

Enabling global multicast functionality by extending support for
what's already there to include use on wireless nodes is not _quite_
the same thing as getting a single instance of an ad-hoc-specific
flooding protocol working for the wireless C++ code...

imo.
