The supported maximum number of sites in any configuration on all Cobalt
RaQs is 200.  To the best of my knowledge this limit is not enforced on
RaQ 2, 3 or 4.  The user interface on RaQ 3 and 4's use an SQL database
(postgres!) as a backend and scale very well for large numbers of
sites.  The most common system limitation when using more than 200 sites
is Apache's inability to support more than ~250 unique IP addresses.

There are very efficient, and unsupported, ways to configure Apache to
serve 10,000+ small web sites on a RaQ if don't need all the
functionality of Cobalt-configured virtual sites.  You'll have to read
up on Apache and Linux before hacking away at system configuration
files.
