I'm sure you already know this --- but just to be clear --- Bobby and I 
are managing different SAMRAI-PETSc wrapper codes, which are in turn 
used in different application codes.

What I'd really like to do is to setup some SAMRAI stuff that actually 
uses Vec / Mat for data storage, so that most of this wrapper stuff is 
not necessary.  (It would probably still be necessary to have a wrapper 
for VecNorm, but that might be the only one.)  Of course, I've been 
wanting to do this for years now...
