You confuse between IP address and request host. The VHM (or any system like
it) does not care in the least about what address a name resolves to - all
they look at is what host was the request sent to.
As you read in earlier replies, all you need to do is to map (in VHM) between
a host NAME and a Folder. If you use Pound to separate between hosts (which
is not really necessary) you only need one mapping in the VHM, but you can
have as many as you wish.

No. Your current setup is fine.

That assumption is not really warranted...
