I know it is NAT-like.  Why the hangup with experimental?  NAT
isn't on the standards track either, its informational, and that
hasn't stopped its wide spread adoption.  My understanding from
one of the RSIP authors is that it was made experimental so as to
not be seen as an alternative to wide spread IPv6 adoption.

I'm not aware of any v6 RSIP implementations either.  And I've only
seen one Linux v4 RSIP implementation.  A BSD version might make a
good SoC project.
