I don't think the price of the tutorials are bad at all in the first place.. so getting points for a different sight is not that big a deal in my opinion. I mean, photoshop cost how much ? and Maya ? You know sometimes I think that might be part of the problem. the Programs cost so much it leaves you feeling like damn, they have a long ways to go in showing me how to use it...

just .02

BTW I don't think transferable points is a bad idea in its self but I think that it would be a overburdening hassle to code that ability in to different sights and databases.
