The latest work on this was done by David Kopf to get ContikiMAC

http://git.devl.org/?p=malvira/contiki-2.x.git;a=shortlog;h=refs/heads/dak-contikimac-rebase
That was done about a year ago. I do plan to merge this in eventually,
just haven't gotten around to taking another pass on radio cycling
yet.

I haven't seen any work done on ED. But I'm pretty sure Beekit does it
