[VLAN] broadcasts go where?

No, not necessary, just a simple list of routes.

Well, Ben, Peter and James are unanimous even in the wording :-)

I agree the cleanest way is to use separate IP networks but I'm using
about 65 vlans for now, and it may increase in the future. This means
I cannot do it without using invalid addresses so I preferred the other
way.

I'll have a look at bridging all vlans and using iptables/ebtables to
control traffic. It might be feasible if the number of rules doesn't
get too large.

As for explaining what I'm doing, I think you've all understood it but
maybe you don't believe it :-) It's really just the opposite of the usual:
instead of having each machine be able to talk to every other (this is
what the switch does), restrict communication to each machine <-> servers
only, plus some groups.

Thanks a lot for the good answers.
