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.

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.

I agree. VNC was originally conceived to do this -- keep a user's session (and data) open on a server while the user roamed from room to room, PC to PC. It works great in a local/LAN environment, though maybe wastes some local PC power if the PCs are full-blown desktops.

The big drawback is the requirement for full-time network connectivity, which might be an issue while traveling and such. But I can live with having to copy my files in that case. Migrating several GB worth of OS, data and session every time I switch machines seems rather inefficient.

I want to set something up like this at home as well. I haven't seen VNC or RDP support things like streaming video very well, but I guess that will come. A hybrid approach would be fine, too -- remote control, remote HTTP proxying, or all local, as the needs dictate.
