OpenBeOS (under the MIT license) is writing the code and maintaining the source trees. Phase one is to recreate BeOS Version 5. Phase 2 (called glass elevator) will begin to improve and extend the new code. Phase one is going on 2 years and seems to be building speed (about 2/3 complete by 53 different contributors). As sections are completed they can be used and tested with the original V5.0 code.
