I am currently running Ubuntu 10.10 on new Dual Core Neo II Acer Aspire notebook. It works!!! The only bad part is the laptop's webcam is kinda laggy on IWrelay.com "Cloud relay". If I sign fast, it'll wash out my sign. The operator's video on screen is smooth, no issue. I plugged and tested my USB Logitech Vision Pro (driverless webcam for Mac) and it is very smooth self view. Apparently that laptop's webcam is sucky!! I wish I can swap the webcam for better one!!
So IWRelay "Cloud relay" is the best option for Linux users!!
