You can run as many virtual services as you want on a director provided that 
each service is uniquely identifiable (either via proto/VIP:port tuple or by 
fwmark). We have mutliple HTTP services on different IPs and one some of these 
there are also load-balanced FTP servers.

I really don't know what that config script does, since we use ldirectord to 
set up production services (and test servies are added by hand).

If in doubt, try ldirectord. It also does adding/removing real servers 
according to their availability (really useful if you want to fully benfit of 
loadbalancing). Config is quite easy.
