Ah, yeah, don't do a surface on a protein!!!! This has to run though all 
PAIRS of atoms looking for overlaps. The presumption is that you want to 
do the solvent-accessible surface on a small portion of a protein -- 
that's no problem, as the algorithm just scans the immediate vacinity of 
the selected atoms.

  select 1-3; isosurface solvent

for example. I don't think we stand a chance to do the solvent 
isosurface for a whole protein. Just too big.

sure, I think so.
