Since we discussed this privately, I can answer this on behalf of our
team: yes, we're interested, but this is a lot of effort.  Funding of
such efforts at a commercial level would help.  As volunteers and using
our own funds, we might proceed to target newer hardware only if it
seems very lucrative in some way(s) to do so - such as results way
better than what we already have - and even then it's difficult.  Just
to support more boards, no.

If your company or you personally, if you got rich on Bitcoin or such,
are in a position to fund a project to support VCU1525/BCU1525 boards
and Amazon AWS F1 instances, let us know.  This idea has been on hold
for a long while now.

I assume you mean for password cracking.  I am not aware of other
current efforts.  (There have been some past efforts.)

That's true, although I'm puzzled as to where all those boards went.
Maybe some can still be obtained by asking in the right places.
