Can you detail some of the requirements? Whatever you use will require a
protocol of some sort, and the network stack already implements almost
anything you would want. Possibly the next best thing would be to run
another protocol (eg not tcp/ip) over the virtual ethernet.

If you can state why using a network is out of the question, you'll
avoid a whole load of people asking you :)
