I'm still in a league that is pen and paper (been going for 16 years now; I've been in it for 3) and I've always enjoyed it.
Let me tell you what I'm going to do if this actually happens...
It would be very simple to create a sort of P2P client that allows people to submit stats. Create a xml based template to build your scoring system and run the stats through it. It would calculate the scores for the league and then the scores could be posted on a shared website. Since the scores aren't owned by the NFL (if they get them) there's nobody to sue.
Hell, I need to start working on this so I can make some cash somehow.
