Sourceforge is the best place to look for interesting projects. A quick search revealed me at least three borning projects about VMware and Virtual Server:

– vmware-magic
vmware-magic is a set of shell scripts to provide a computer lab with the ability to maintain sets of VMware images on a central server for archival and distribution within the lab. The scripts provide for users to have access to their images from any machine

– VMware Consolidated MUI
The purpose of this project is to create a consolidated VMware GSX/ESX web-based management interface using XML and XSL, together with Perl and Apache.
