you're running gated on them?

noone's found the limit yet. People aren't looking real hard
since you can saturate almost any link to the internet with
just a couple of realservers.

No-one's found it. In the early days someone ran 1024
realservers by putting multiple RIPs on 4 boxes. Not quite
the same thing, but a test at least.

what are they? No-one's talked about them on the mailing
list.

The director is just a router with slightly strange rules.
It's just forwarding packets and all it's concerned with is
bandwidth. I wouldn't expect it to cause any problems
However I don't know of anyone running 80 realservers with
millions of connections.
