Stephen,

Thanks for your continued interest.  We _are_ going to address the latency
and Jan has begun working with us precisely to address the issue of
strange disconnections and better reintegration.  In the longer run the VM
size will go down dramatically too, but that is really longer term.  A
clear message in the rvm setup can be incorporated.
