I can't say much more than what has already been said about VMWare announcing long distance VMotion capabilities up to 200km but I had some quick thoughts about it and figured I would put it down here.
It is nice to see Cisco, EMC and VMWare teaming up on this but right now it has some serious limitations. Minimum bandwidth of 622 Mbits/sec isn't quite too bad. In my mind 5 ms latency is pretty low.. At this point it might be useful for evacuation to some kind of disaster recovery site with a bigger pipe, but not quite a 'follow the sun' approach between datacenters. When they figure out how to deal with higher latency and are able to go inter-continental with Vmotion this will change the way global companies IT operations work!
Here is a video demonstration done at VMWorld by Chad Sakac with EMC:
