I talked to Casey tonight, and will be attempting to update it for a
release for beta6.  This will be done via the sf project since I am now
a developer there as well.  In any case, there is going to be a bit of
leg work, so don't hold your breath expecting it to come out right when
beta6 does ;)

Anything further on this?
