VMware Labs released a new Fling called WebCommander. The download is available as ZIP and is about 1.2MB.

Quote taken from the Fling page:

Have you ever wanted to give your users access to certain virtual infrastructure tasks instead of the entire vCenter Client?

WebCommander is a way to do this! WebCommander was designed as a framework to wrap your PowerShell and PowerCLI scripts into an easy-to-access web service. Now you can hand off the tasks your users need by simply adding a new script and giving them access to WebCommander.
