I certainly don't live bet everyday, but I definitely use the feature at WSEX and sometimes at matchbook. I think I'd need a lot bigger bankroll if I was going to do it more. I'd like to see more games offered.
I've been using it for the conference tourneys at matchbook, but i have only used it to hedge games a bit. Been able to turn a 150 to win 150 bet into like a 4 to win 100 when my team was only covering by a few points.
