I wasn't talking about a default gateway.  I was talking about a set of
squid proxies.  Without using mPPP or some other load balancing solution
you're just going to be pissing in the wind trying to get the entire
network of machines to use all four gateways at once.  Setting four
different gateways (considering that all four are likely to be
masquerading) is going to be pretty thoroughly inefficient.  If you
configure up squid proxies you'll probably eliminate 80% of your user
complaints.  (Setting up SOCKS on them all would probably be a good idea,
too, but likely to create as many confused users as it fixes).

As an escapee of the PhreakNIC conventions back in Tennessee, I have a bit
of experience with watching people try to duct tape and velcro-strap a
bunch of different (and all rather weak) internet connections together.  
You're up against a bit of a technical wall unless your Ricochet provider
can hook you up with mPPP.  Setting up four squid and socks proxies, a
DHCP server, and a caching named with private zone or two should take you
approximately less than a day and let you get on with your other tasks
with mimumum delay without investing a lot of time an effort into a
configuration you're going to be changing in a short while anyway.
