That's what I was guessing.  My example turned this logic around,
which I think is a better idea:
if (SERVER_NAME in vhost.map)
   redirect to map target
else
   serve from /var/www/hosts/SERVER_NAME

In either case, the results are undefined for hosts which are neither
in vhost.map nor under /var/www/hosts.  But my logic is faster and
simpler.

This doesn't do what the comment says.  I think you are looking for
the -f option to RewriteCond.  But it is best to avoid these kind of
tests, which is what I did in my example.

This line is unnecessary.  The lookup can be put directly in the RewriteRule.

The QSA is unnecessary since you aren't changing the query string. 
The original one will get sent automatically.
