From what I understood the problem is the lack of a driver, so if anyone writes one for AOS4.1 or for a backport of Poseidon from AROS it should be possible.
The question is if there is enouph market for another run, I think there is but it will take sometime to sell.
Also, if there's no need to pay for licensing a USB stack anymore then it could be sold cheaper. This is probably where they both had a disagreement but the truth is that the stack is now open source and the drivers are not, so drivers could be written.
