It's not too tough a port, though.  We've been incorporating hhnet into
the kernel when we do a major release, and haven't been updating the
separate package on the FTP site.

Yes.

One of the reasons we haven't been extending hhnet significantly is
that we've been working with PICMG, the CompactPCI standards group, to
develop a backplane networking standard.  The new standard will allow
communication between different OS's and architectures.  (hhnet works
with multiple architectures, but only on Linux.)  We expect that when
it's complete this new standard will supplant hhnet for most
applications.
