Check out what Carter Shanklin just posted to the VI-Toolkit forums:

If you have a lot of hosts that you connect to it can be frustrating to remember them all. Since I have this problem I wrote this function to help deal with it. If you use the VI Client, connections are stored in the registry. This function reads these entries and presents you with a menu where you can select the host you want to connect to. Hopefully the forum doesn’t mangle the code too much. I copied this into my Initialize-VIToolkitEnvironment.ps1 file so I get it automatically on startup.
