After the whole NETeller debacle, I would be wary of association with anyone providing service to online betting shops.

Blame those who caused this, not the companies.
Regardless of where you stand on the issue (and I'm obviously as pro-gaming as they get, since I made my living for 5 years playing poker online) the fact is that the DoJ is going to systematically destroy anyone who has anything to do with online gambling. Anyone starting any startup in that space in this country is begging for jail time.
It would need to prove stable but it might be enough to give Paypal or any other fund processor (online banks even?) a real run for their money.
