Hey Kapil,

I can report some progress on the points you've asked about:
1) non-default VPC support is mostly done - see bug
https://bugs.launchpad.net/juju-core/+bug/1321442, which I have mostly
finished fixing. In brief, there will be a "vpc-id" environ setting
that can be used to specify a non-default (but compatible) VPC to use.
By compatible at this stage I mean 2 things: at least one subnet per
AZ, all subnets in the VPC have MapPublicIPOnLaunch set.
2) the AWS VPC support is ongoing in a feature branch, the MVP
proposal will include: add existing subnet to juju (make juju aware of
it); create a space including one or more subnets; deploy a service
within a space.
3) it's on the roadmap to do more sophisticated
routing/ACL/firewalling between spaces, but it won't happen until the
16.04 time frame most likely.

HTH,
Dimiter
