Thanks to Aswath, I discovered a neat hack that allows the enterprising sorts to display Caller ID information on their television screens using open source PVR software called, MythTV. Connect the PC modem to the ATA and you can pick up the incoming caller ID. More details at this MythTV thread. This is going on my weekend to-do list, and will report the results later. There are actually more hacks on the thread including YAC, imaginatively called Yet ANother Caller ID Program which can display incoming caller ID information on a Windows PC and TiVo.
