Yes, MR-AFS is still alive and is heavily used at some sites:
My site: Max-Planck-Institut fuer Plasmaphysik
Universitaet Koeln
Universitaet Magedburg
Technische Universitaet Chemnitz
Navy Research Center, Washington DC

I gave talks about our fileserver environment including MR-AFS on the
Cray-User-Group meetings in Tour (1994) and Fairbanks (1995).

I think it was in 1994 that Transarc had a look on it and found out that
the amount of changes in the source code was too big for them to
support it.

Of course it would be nice to get all this from Transarc, but also by
merging all new standard AFS releases into the MR-AFS source code we
keep up with the development.
MR-AFS is very important for our site (we have > 5.6 TB in MR-AFS).
Therefor we do the development of new features for MR-AFS and the
merging of standard AFS features here at ipp-garching.mpg.de and give
all who have the AFS source license and a lincense agreement with PSC
access to the source.
