I've been trying to get the isis/Horus/Ensemble distributed
simultaneous group broadcast code released as freely redistributable,
including sending some calculated flames.  My understanding is it will
make writing distributed transactions utterly trivial.

Right now you can pick it up from  However
it's encrypted, requires a per-user license, and the distribution is
incomplete.  It's not at all clear if it's freely redistributable in
cleartext.  I'm hiring one of the core developers to clean up the
distribution, and I hope the license conditions will be improved.

More news when I know it.
