OK.  You mentioned in your first email that you were using XenClient, so 
I assumed you were executing VMs on client systems.

It's intended as a scalability measure in general.  Within a university 
campus, the response time of a thin client system will likely be 
acceptable.  But we believe that an executable archive will eventually 
serve users around the world, and thin clients quickly become unusable 
when the client and server are far apart.
