I live in Atlanta, GA (Dunwoody) and would love to see a wireless community get started here. The problem is that cable is primarily controlled by AT&T Broadband and DSL is primarily controlled by Earthlink and Bell South. Each of these organizations have Acceptable Use Policies which strictly prevent their customers from "sharing" connections legally. If anyone has any suggestions on how to accomplish it legally in the metro Atlanta area, please chime in!

Here's a diagram of how my home system is setup:
