vm4all.com: Tools for VMware ESX server and Virtual Center

...provides a list of tools for VMware's ESX (the high end enterprise-grade virtualization product) and Virtual Center (the high end hypervisor management product). Not all of the tools listed are free. However, many are. If you use VMware ESX with Virtual Center, you definitely want to check out this site's list.

I wonder if there is a similar list for tools related to either Virtual Server (VMware's freeware server product), VMware Workstation/ACE (Windows/Linux product), or VMware Fusion (Mac OS X product)?
