Hi All,
My 2c worth...
If a network is defined by names, addresses and policies then all networks
are virtual. What you use them for and how they use pathways is less so,
but I don't want to get bogged down in that. Jon's problems seem fine to me
for now.

This combination is in widespread use already in industry - I'm not sure if
I'm allowed to say who - but one of my students, who is sponsored by a
well-known global telco - set a xen+xorp+click system up for me based on
what he did last summer for his sponsor.
Xen multiplies your capability by as many instances as you can run. Its a
solution now.

There is a certain community that attends Cosener's and probably we could
do better in enrolling a wider group. Probably many of us have tried.
What's the obstacle to engagement?
I have a theory about this: good ole politics and silo thinking. For
example, when EPSRC did its ICT review, Bristol EE and CS piped up loudly
to complain that we weren't on the itinerary. The first response was: you
are Engineering not ICT, and you have *relatively* little EPSRC funding.
Neither being true, and passing over a series of constructive discussions,
we think we have a better understanding now, but it took effort.
Maybe putting this effort in should be part of this response we are
formulating.
Regards,
Alistair
