If we had such a driver, I'm sure it would have been released with the
IEEE 802.11 stack. Not being from this world part was referring to us
not having this kind of functionality for Prism2/2.5/3..
There is a _very_ old version of Prism2 driver for the IEEE 802.11 stack
and I don't think there would be any issues in releasing it, but then
again, it has never really been used in products and it has not been
updated for couple of years (i.e., it would be unlikely to work with the
current 802.11 stack version) and it does not have any extra
functionality over the current Host AP driver, so I don't see much point
in anyone using it.

Difficult to release something that we don't have..

That may be the case, but I haven't even seen that firmware nor a driver
that would be using it. I would be very much interested in getting a
freely available version of said firmware and driver, if someone were to
be in position to release them.
