So you're going to have hosts like host1.foo.bar.com, host2.foo.bar.com,
etc.?  In that case, just put a normal delegation in the bar.com domain:

foo IN NS ns.foo.bar.com.

ns.foo IN A A.B.C.D

In the named.conf file of your box you put:

zone "foo.bar.com" {
  type master;
  file "db.foo";
};

and fill in the db.foo file with all the data for your subdomain.

Isn't this explained well in the "Parenting" chapter of the DNS & BIND
book?
