Yes... well sort of.  I mean you don't have to have mod_proxy, it's
more or less built into Apache to allow you to associate different roots
with different names (virtual hosting).  We do it at work all the time
to handle "historical" stuff.  Then you don't have to have more than
one VM... if all you're interested in is web.  But as you said, you
can frontend it I suppose so that there is a real VM out there (purpose
unknown to me though).

I guess without knowing completely what you are wanting to accomplish
it's difficult to suggest a solution (?).

Definitely.  Just not always an option.
