Some time back, I was introduced to the word 'Teleportation' in the context of IBM. IBM research has been working on the concept of Teleportation that aims of disintegrate an object at one place and reappear intact in another place (with out physical movement of the object). Can you believe?

If that research becomes successful, can physical objects be sent from one place to another (without physically transfering them)?. I think the logistics/courier companies would go bankrupt, I guess. :-)

I happened to see the same word in a different context few days before. Very similar - Sun's new virtualization software has introduced a new feature - called "Teleportation". Using this feature, end users would be able to migrate "live" and "running" virtual machines from one host to another. The source and target hosts can run on different processors and different operating systems. Still, the the VMs can be migrated seamlessly from one host to another. They call this feature as 'Teleportation'. VMWare offers this feature in the name of 'Vmotion'.

Using this feature, downtime of servers can nearly be eliminated, especially when servers have to be rebooted or during scheduled maintenance/upgrades.
