Hmm... I cheated though :-)

I use a Linux boxen for the dialup itself. I would NEVER use a Linux box
as a main router, because the simple fact is, they are more prone to misc.
hardware failures than a Cisco router. (not that Cisco routers are
indestructable or anything)

Aha... I am a Holy Linux supporter, but I have no beef with any truly free

I beleive that freebsd can still do transparent proxying somehow... But I
don't know.

I have a customer support page, which will tell customers how to set up
the java proxy autoconfig.

Hehehe... Netscape are a little bit more security concious than that :-)

They will have to do it manually.

As for IE, you can just give customers a .ins file which will set
everything up (Start page, search page, dialup+scripting, proxies etc.)

This comes with the IEAK.

I don't recommend transparent proxying, this is just to catch those that
slip through the cracks once you beleive that most are using the proxy.
