Ok so just an idea that sounds like it would be fun and bring in lots o miners..
![Grin](https://bitcointalk.org/Smileys/default/grin.gif)
0% fees, BUT when each block is solved you take 1/2 of the trans fees and have a lottery where one miner wins this. (all automated)
That way even slow to midrange miners have a chance at a nice bonus payment.
Would work like this = randomly pick 1 share submitted and pay the bonus.
This way anyone contributing more shares would have a higher chance, BUT everyone would have a chance.
Think it would be a very popular pool and have the added bonus of the 'casino' feel. Would make mining more interesting to me, for sure!
