I take it this requires a router that can hold _all_ the routes on the
'net... mine does BGP4, but can't hold all these routes.

I'm not real concerned with the bandwidth squid uses to ask for webpages,
I am concerned with load balancing the bandwidth of the webpages coming
_back_ into my network. The way BGP is currently set up with my
upstreams, bandwidth from ISP1's IP addresses come back on ISP2's
interface... and bandwidth from ISP2's IP addresses come back on ISP1's
interface... so if squid could produce requests with different source IP
addresses, load balancing could be achieved, at least coming into my
network... This is why I'm thinking of running two Squids on one machine,
either useing two NICs or two virtual interfaces... but I cannot figure
how to get the two squids to speak to each other, so squid1 isn't
retrieving objects that are in squid2's cache. Plus I need to configure
this mess to use Cidera... ;-)

I hate to be ignorant, but I still cannot see the error of my logic.
