Please add me also.
At the moment I’m playing with the “IP Webcam” app on an old Android phone (Wi-Fi only). The app works great, now trying to figure out a way to send a text, tweet or email when it detects motion. Fun project.
You can also use Presence for turning an old phone into an IP camera; takes a bit of work to get the settings right however. It will auto-notify and save film snippets for you.
