Ian started another thread on a similar topic: IF Driftwood and/or TRoS were for sale, how much would any volunteers be willing to chip in? I for one would be willing to chip in a fat chunk of change if it would mean the chance to attempt to negotiate copyright & publishing permission.
There are a few things operating against this:
1) George isn't interested in selling. I don't mean that he actively wants to retain the rights -- I mean he has lost interest in TRoS from a business perspective.
2) Blade of the Iron Throne will be released by the middle of the year. It is an excellent successor game with a wicked setting.
3) Jake's new game is on the horizon. If it gets up it should be out by the end of the year.
We would have bought the rights long ago if they had been available to buy -- but they aren't. As a communit we've moved on, creating our own successor game and eagerly awaiting Jake's. When they are both available my personal opinion is that TRoS won't be worth anything to anyone because there will be much better options available, one of which will be free.
