You can now also turn your Hero into a wireless router using
Wireless Tether (aka wifi tether).. previously was only working on the MoDaCo ROM, but the developer has released a new "pre-version" of Wireless Tether that works on the stock Sprint HTC Hero ROM (with root access, obviously)! As per user capnbry, "..the problem is that the gprs table has a default route on it, and it has a higher priority than main, which is where the wireless route goes. If you `ip route delete table gprs` after starting android.tether everything works like a charm." The developer has added this step into the program, and it works!
See
the thread for details, or download the new "pre-version" here:

Hope that helps!
