I'm looking to buy a digital camcorder that also works as a webcam. My girlfriend is leaving for Australia to study on an academic scholarship for 9 months (getting her Master's degree in just two semesters) and we want to be able to communicate through webcams, but I'd also like to be able to buy her a camcorder that will allow her to chronicle her trip. Any suggestions? A friend recommended Canon's ZR300 or ZR400, but he wasn't positive if they would work as a webcam on a Mac. She is using a Mac, I'm using a PC. From what I've read, I think we should be able to link up if she uses iChat and I use AIM Triton. I just want to make sure she'll be able to use the digital camcorder as a webcam before I shell out the 350-400 bucks I'm willing to spend. ANY HELP? PLEASE???
