I wouldn't be surprised if there is some kind of support for this in for example SLP (Service Location Protocol).
The general idea, as we understand it, is to have several clusters on different geographical locations, and then have the system automatically select the nearest cluster. Tarantella has/had something like this. I think this could be implemented in several ways. Some ideas: * Add this functionality to VSM and perhaps construct some kind of "super VSM server". * Use DNS in some clever way. Either we could provide a special DNS server which returns different IPs depending on the client IP/distance/latency. Or, we could perhaps use a standard DNS server returning multiple adresses and then add functionality to client to determine which adress is nearest/fastest.
This might be important if a cloud provider wants to deploy ThinLinc. They generally have data centers all over the world, and might want to offer a global service. Routing users to the data center with a reasonable latency is then key.
