Fixing the Nakamura event

I'm sure people have a lot of suggestions for avoiding the disaster that happened today when chess.com made the ill-advised decision to advertise what they knew would be a popular event without preparing for the high probability that it would crash their servers. But here's my two cents:

- Make the challenges open to diamond members only

- Make the live viewing open to premium members only

- Make the video of the event publically available for 48 hours on chess.com and youtube; afterward, video is available only to diamond members (maybe make 3 games available to premium members.

Feel free to offer more suggestions below. I assume there's no point in paying for the necessary server bandwidth, unless the site can arrange to pay for just a day's worth of the appropriate bandwidth. 

EDIT: (In reply to EnjoyTheChess) Another option, of course, is to keep it open to all but have people people sign up to be part of the challenge pool and then select them in advance. A pool of 500 players would probably be manageable and give more than enough opportunities for challenges. 

Democracy's well and good in theory, but we have to remember that this event basically didn't happen because chess.com can't handle this particular kind of democratic process. That's a loss for everyone. 

Im not up with closing the challenge to only some players, I really liked the democratic character of the event today, that everyone could challenge him...
