You should probably e-mail Henry directly. I know he originally had hoped to have time to do the bboard port, too, but then his life got taken over by (I think) a Real Life Gig leaving him insufficient time to do so.
So it goes - I've had to cut back my efforts on OpenACS 4.x because of a client gig, myself.
Anyway, he's not been hanging out here recently, at least on a regular basis, thus the suggestion that you e-mail him directly.
