It seems Lauda is prompt to answer this query, just make me think Lauda aside from being one of the escrow is also a part of the development team.  Well, having Lauda in the team would boost trust on this project.  Anyway, I think that unpopular and unstable altcoin will not be accepted as payment for this project.

OT:

PSB dev is still active and they still have recent updates on their project, they might be unstable and not popular but I believe, saying it is practically dead somehow brings misinformation.
