Is there a VN Technology Gap?

State-of-the-art
– How do I setup a VN in the same time it takes to open a
socket/bind or RPC?
– What is the middleware glue to do this?

Where are we today in the field?
– TEMPEST, NETSCRIPT and X-Bone

Genesis
– The middleware: a virtual network operating system?
– Profiling, spawning, managing, architecting
