Dont worry, I've contacted with ZVRS myself and sent them strong messaged Email about Z4 for Linux. I willl wait and see what they say.
I've ran Windows base Z4 on Wines, It loads but won't run. I tried VMWare for Linux and installed Windows inside of it. Installed Z4 in it and ran it. It works but LAGGY at best!!
That's what pissing me off!!
Skype provided VideoChat for Linux and works great. I have Driverless Logitech Webcam and it works great (it's Logitech Vision Pro for Mac)
Webcam work fine on my Dell Mini under Ubuntu.
