VirtuePup (maintained by DrZer) is a version of Puppy that runs in VMware. It is tweaked to run good in a VM.
Zer plans to release updates to it as often as possible, closely following the main Puppy releases.
The first version will be done by Sunday or Monday and will be based of 2.14.

It was started mainly because the puppy VM hasn't been updated since 1.07, and because I was bored.
