Voip News has a nice article on 25 tips to Improve your skype experience. I liked this one:
Whether you want to keep an eye on your pet goldfish from work or just make sure no one has broken in the house while you are on vacation, Skype can double as an away from home monitoring system. Checking in is simple with Skype’s one and two way video calling. You’ll need two separate Skype accounts, a computer at home with a webcam, and access to the Internet. Using one account, setup the home version of Skype to auto-answer calls and automatically fire up the webcam. Then to check in, just use the second Skype account to call the first, and the webcam video will pop up.
