This is more of a question than an answer.  Can TMPov just be used with the
modified pvengine.exe like the isosurface patch?  If so, then you could run it
from a different directory without touching your current installation.  All the
preferences will be the same.  That's the way I use the iso surface patch and
haven't had a problem.
