Do we have any of the necessary software parts to do simulated ATM hardware similar to what if_tap does for Ethernet? Using the VIMAGE stuff and virtual ATM hardware might open up the door to a more accessible development and test environment. I did the NATM locking work essentially "blind" due to a lack of test environment locally, which seemed to work out, but a software test system would go a long way.
