Yes, been there done that. That is exactly what we do for most webhosting
clients, since the mail server is usually the same, and since it is
virtual hosting for most clients, the IPs are the same. Clients that
request a dedicated IP or get higher range webhosting plans get a
dedicated IP (don't people realize there isn't this huge perceived
difference!?)

That is what we want to avoid. The thing is... we don't really want to
clutter our BIND config. with people just parking their domain names. Why
not just give them a particular "default" IP that everything points to,
and be done with it, rather than adding hundreds of entries for people
paying either nothing or $5 a year (you get the picture...). We have no
problem adding it for "real" clients, but parking domains seems a waste of
BIND config space.
I know that with some of the large domain registrars, if you point your
domain name to their parking DNS servers, a webpage shows up, regardless
of whether you informed them that you were going to park your domain
there. So that proves the above point *CAN* be done.
The question is... how....
