Just a thought...
Inspired by the simple fact that the Stars check I received had PokerStars written on its face. Add in the nagging suspicion that the only thing the sites ever had to do was just that, put their own names on the checks.
Since this whole case involves the movement of money, and some questionable practices, and NOT about the legality of online poker, I think FullTilt should re-open gaming to US players who already have an account. They can prevent new deposits from US players until something comes along to clarify things, and they can pursue helping along things that will help clarify things.
For FT it would mean a large consolidation of the US players money. Many will go belly up, and be unable to continue. A choice that only affects whether they can deposit means they can still play.
For simplicities sake let me use a number of 100 players with limited bankrolls. Also for simplicities sake lets assume they each have the same bankroll. Very shortly after they resume playing, there would be only 50 bankrolled players, shortly after that 25, then 10, etc. In the end there might only be one. FT would have reduced the volume of complaints, without reducing its financial liability, so things could be much simpler.
In the meantime, FT has collected rake or fees, hopefully regained some lost reputation, and until that one remaining player wants his money (a fairly substantial sum by that point) FT has no payout issues at all.
Since the player experience is extremely important, like how many of us like the bodog experience, or the Zen experience or the Merge experience compared to the Stars or Tilt, or even Cereus experience we know we prefer the software of the sites that have abandoned us. And because of this, US players will flock to Tilt. Might be the nittiest play ever, but we would return, full force.
Also in the meantime, all the gears and fallout over the BF disaster can be sorted out.
