Have you ever wanted to share your desktop with another user somewhere on the Internet or in another office?  There are a few tools available to do this but I recently found Microsoft SharedView.  This is great free utility that works everytime. 

You can share your whole desktop or just a single window with as many users as you like.  You can grant control to any of those users and chat with them online.  Users connect via HTTP over port 80 and are authenticated with a Live login so it's pretty safe.

I've found this a life save several times recently, most recently today when I needed someone in our Wellington office to configure a VM on my local machine.  Access through the domain wasn't working for some reason - firewall issues or something like that - but SharedView just cut through the noise brilliantly.

Check it out!
