Yup, been here too (I've been working on this problem for a while before
getting suck into this).
For a public cloud like EH things are pretty simple - you just give an IP to
a machine and away you go... they can talk to each other and if you must
then you can pop a firewall/load balancer in front.
For anything more complex though you do need to keep track of your [virtual]
networks separately, even if only because the client needs to be able to
enumerate them in order to give the users something to strap their VMs to
and (on the system management side) to link to a physical segment.
I'm not sure what really needs to be configured here beyond a
label/description, but it's conceivable that a network management extension
would be interesting for vendors like Cisco.
