I did some reading on active-active and while I think its a great idea,
I didn't quite understand how it was capable of doubling the throughput

Horms would be the final word on the matter, but he seems to
be busy (hasn't popped up on the mailing list for a few
weeks). I haven't read the Saru docs for a couple of years
and you seem to have read them thoroughly and I assume
you've got it right.
n active directors can handle n times the bandwidth, but you
have to send it to them. You'll need 10GigE (or something
like that) in front of them.
I didn't know that the directors had iptables rules infront
of them to divide the work load. One of the requirements is
to load balance and handle failover, so there must be at
least two directors capable of handling any particular
stream of traffic.
