I'm interested in the speakerphone possibilities...
>There is also a webcam driver available from QNX.com which I have not had time to play with either. If it works, I want to be able to view who is at the door and make video calls over the internet.
Only issue I see here is that since USB is limited distance (15' without a booster??), you'd have to have your Audrey pretty close to the door so the camera could see them. Another option might be a standard RCA camera to a video capture card in a PC (or an X11 wireless cam to the capture card, but watch out for WiFi (802.11b) interference) and then you can stream that to to the Audrey.
Some of the systems (I got a low end B/W system a Costco, supports 4 cams with Audio and motion sensor a bit a go) also support triggers. So you could hook a relay to a serial or parralel port, and trigger something (launch Audrey video/audio 2way??) based on motion detection, or just do something similar off of the doorbell.
Of course, if you have 2 or more Audreys, you can mount one on/near your door for the cam stuff, and the other one could be the remote end.
Or the remote end could be a home theater PC. With a tuner and a capture card (or just a streamed source), the audrey video could pop up in a PIP window on your TV. If you multicast, you could have it pop up on all your PCs.. Hey.. er.. Going too far now?? Sorry..
It's too bad the CF slot isn't better supported. A CF WiFi card and a USB camera would make a nice remote monitoring system.
Heck, I just got my Audrey playing MP3's.. :)
