what is this josem thing you speak of?
You continually want to conflate two independent things.
thingy #1. an online site using a crypto currency for cashiering.
thingy #2 a common, open source, pseudo coded, shared , p2p based backend solution thingy used by many operators.
I am quite sure thingy #1 is already happening and will continue to happen more and more.
I am leaning toward thingy #2 not happening in the foreseeable future.
Thingy #1 is not dependent on thingy #2.
There is value in thingy #1
I still have not seen any value in thingy #2 (unless I were to believe that thingy #2 suddenly makes online poker legal everywhere. p.s. I don't believe that)
