I also believe that one day (perhaps in January?) they'll allow post June 20, 2010 resales to be enrolled ---- but only if you buy X,XXX Trust Points at the same time. Starwood does this (they call it requalifying your resale) and people with high point properties do buy direct from Starwood as part of a calculated move to get the points for their resale.
I think the little spreadsheet that TUGgers helped to compile last year would be useful for this exercise (it's the spreadsheet below at gtibbitts.tripod.com).
Please let us know if you hear anything more, and we will do the same.
Best,
Greg
