Others have responded to this already with good points which I won't repeat.

Personally I don't believe we should try to convice everyone to agree on
one backup system.  I believe that would be a huge shot in our collective
AFS foot.  If we want AFS to spread we need to have it play nicely with
as many backup systems as possible.  Many sites have local guidelines/
requirements/mandates about what their backup system ought to/should/must
be.  Why make this a stumbling block in the "can we do this?" check list?

I see this as more of a general purpose than an amanda-specific feature.
It's a "If I vos dump this volume now, how big will the resulting dump
file be?" feature.  Any backup system that uses vos dump to backup AFS
will be able to use it.
