Check out this blog post by Carter @ VMware.  Great stuff!

The PowerGUI VMware PowerPack has lots of great features, including the ability to manage your ESX Hosts and VMs, as well as doing bulk operations. In my opinion, PowerGUI’s best feature is that as you interact with PowerGUI, it generates PowerShell code as you go. You can take this code and re-run it later or you can parameterize it and turn it into a script. This is especially great if you’re not a hard-core scripter, or if you aren’t very familiar with PowerShell.

Hmmph, can’t figure out how to make it connect to the server.  I tried making a script node with this snippet: Get-ViServer (read-host “Server Name”).  No luck.  Will mess more with it later.
