status of Air-Borne Laser programme?

Does anybody have any recent info on the stauts of the ABL programme?
The latest I know is that the YAL-1 prototype has been flown, though as
yet without many of the systems installed), production representative
equipment was being installed in the fuselage of a grounded ex-Air India
B747 and funds have been allocated for acquisition of a second 747-400
to serve as the first production aircraft.
Any info on whether systems integration is proceeding as planned and on
whether the HEL laser modules are up to spec?
When will a functioning system be installed on the YAL-1 prototype?
The ABL webpage www.airbornelaser.com sadly provides little info.
