For those who haven't yet tried the Vision self-paced labs, they are well worth a look!
I expected simple VMWare Player shortcuts on the desktop, so what I saw impressed the hell out of me. The desktop just has an IE shortcut where you register to use the VMs with a username and password. You can then select you lab and in the background on a server you own VMs are generated. The dual-screen setup also allows you to throw up the lab pdf on one screen, whilst you get to work on the other.
These VMs are accessed through the browser -nothing is local. This means you can do half-an-hour over lunch, logout and come back later to your VMs just as you left them.
This is a sterling service, and a very practical solution to providing Vision labs when large blocks of free time are hard to come by!
There are currently 5 labs on there, and more labs are added daily. This is the first of its kind at Vision, so try it out (and leave your email address for feedback!)
