You should be able to use dummy network devices for this.
They are basically equivalent to private bridges, but like you said
are loopback and don't need to be associated with a physical NIC.
Alternatively, you can create bridges manually and add devices to them.
You can then just put the brctl commands in a script.

Hope that helps.

Cheers,
Todd
