If this is NL then the buyins should change with every level change and there should be a normal maximum buyin (no matter what format it is). Having a 10/20NL player sit with $10,000 during the 25c/50c level would be annoying. If it is limit then it doesn't matter. At the end of a level you could either keep what you have on the table (even if it is above the maximum--not that it would be that much above) OR top off to the max for the next level if you want.

I like the idea of incorporating a prize with a buyin SNG style (or MTT style, but that would be confusing). Not sure how you would keep track of who is winning though...

MTT, it might make things easier (eliminate voting to continue short handed, waiting for 10th player, etc,etc) if there were a couple of tables of this going on at a time.
