however, you can't place
vhost.com. IN CNAME ...
into a zone for our.real.domain.
maybe it would even work, but you need a separate zone file for each.
whether they actually use A records to point to the IP, or CNAMEs to
point to our.real.domain. doesn't matter in terms of apache. i'd
prefer A records (CNAMEs are said to be deprecated), but in terms of
functionality, they are the same. A records will be more flexible and
transparent...

also, this won't work. hosted-sites is not a zone name. read below.

yes. and yes. let me elaborate on the second.
the named.conf zone statement tells BIND to be authoritative for a zone.
thus, you will have something lik:
zone "our.real.domain" IN {
type master;
file "..."
};
in named.conf. when BIND now gets a request for our.real.domain, it says
"yes, i am surely the right one to ask as i am authoritative for this
domain", and then answers the query with information from the zone file.
if you get a request for www.vhost1.com, then BIND will look for a
statement
zone "vhost1.com" IN {
...
}
but since it can't find it, it then either goes out to obtain the info
from other nameservers (usually not, that's the job of a
resolver/forwarder, not of a name server. BIND can do it though), or it
simply says "sorry, wrong place to ask." it will surely not be smart
enough to remember that you defined vhost1.com. (even with terminating
dot) in our.real.domain.
does this make sense?
