Oracle and SUN Yesterday (today if you're in the US), Sun released the latest version of its virtualisation solution, VirtualBox 3.1. Among speed improvements and other smaller features, the biggest news is that Virtualox 3.1 introduces something called teleportation: you can move running VMs between machines - servers or clients, different architectures, different host operating systems, it doesn't matter to VirtualBox. Coincidentally, this reminded me of an idea I once had about moving running applications between machines.

You're working on your home desktop. You're trying to finish a document you're working on, but you're running a little late. How cool would it be if you could simply "move" the running application to your laptop, without having to worry about transferring the files you're working on?

Or, the other way around. You're on the train, working on a long email on your smartphone. You come home, and of course would prefer to finish the email on your desktop, with proper screen and keyboard. You just tap a button on your phone, and the mail application on your phone moves over to your desktop, where you can continue writing the email right away.

You've described the two scenarios that initially got me using remote desktop - my laptop has effectively acted as a dumb terminal for the last few years, running RDP connected to my desktop.

Granted, it's not as seamless as what you described - things like seamlessrdp help, but there's still a fair bit of setup & "geek-fu" required (ditto for remote X). What you're describing sounds a lot like Citrix, but obviously that's out of the reach of individual consumers.

It seems that the easiest solution, at least with current technology, would be an approach where you have a server in your home that serves applications Citrix-style. As long as you had persistent sessions, you could just run your applications off the server (from within the house or externally).

Personally, I find that approach much more palatable than the everything-in-the-cloud/browsers-as-the-universal-UI-for-everything approach. It also opens the door for less unnecessary duplication of computing power within the home, something I've been thinking about since the last home automation article here.
