I gave up on ICS and went the Proxy Server route with Analogx Proxy
http://www.analogx.com/contents/down...work/proxy.htm
It's freeware, takes up very little system resources, and doesn't require any additional network adapters like ICS.
It will take some work to configure AOL and the like, and you will have to know (or learn) a bit about networking, but it was worth it for me.
About the only thing I haven't figured out (yet) is ICUII - would appreciate any words of wisdom anyone can provide.
