Yes. A series of 'unseen' routers, ELSE a single more complex one,
with your choice of selector mechanism. E.G. - a software Johnson
counter or randomizer.

Probably not *too* much harder to sense who has the least full input
load / unread count....

You should be able to do that w/o external perl - or perhaps just by
reading flags set by an independently running perl (or other) daemon,
SQL in our case, that is monitoring read/unread count or prior delivery
count - but same idea.

from greylisting work, for which there are copious examples.
