I am wondering if it is possible to be connect to a wifi access point without disconnecting from the 3G network. When I am at home i would like to be able to access local resources through wifi, and switching the connection plays havoc with most applications (x-chat, pidgin, etc). I want the default gateway to still be the 3G connection, with the wifi network just available as another network.
I am not afraid of getting dirty with things since I have plenty of linux experience, but mostly wondering if anyone else has done something similar or would have suggestions for a good starting point.
