Just thought of something else to consider.

There is a further issue with setting the owner to resource_group: Networking.  In Vlan mode, each owner gets its own vlan and communication between the instances is easy.  If users start dividing up instances into a bunch of sub-groups we will run out of vlans very quickly.

Network communication between the subgroups will probably be much more complicated as well.  Perhaps some of this can be solved with the multinic / network refactor.  If we can specify at launch which network we want the instance created in instead of keying it off of the owner's network, we might have everything we need.
