It sounds like a very interesting project. Unfortunately, the Kaffe.org project does not hold the copyright for that code, so we wouldn't be able to relicense it. Transvirtual shut down in 2002. At that time, the investors took control of all of Transvirtual's Intellectual Property. Of course, we can still use the code, as it was released under the GPL license. Twin Communications of America took control of the assets in 2003 (according to their website), and they still seem to be around: http://www.twincom.net/ Perhaps you can ask them if they'd be OK with relicensing?
