Ok, so Google doesn't want us to use the OBI to interface with GV but surely they are still allowing Google Chat to use GV.
If I understand that Google Chat correctly it allows the user to make phone calls from the PC using the PC's speakers and microphone.
Given this, is there a device that I can attach to my PC and turn my home phones into the PC's speaker and microphone. Of course I guess ringing would be a problem. I know this requires leaving a pc on but if that's what it takes to retain my GV home phone setup I might just do it.
