There's lotsa rumors flying etc. Industry insiders including lawyers feel that nothing will be done anytime soon regarding this issue.
There are a TON of companies opening that do what paypal did and their not located within u.s. jurisdiction. Bank electronic funds transfers work too. If something does happen though, its not likely for at least a couple years and by that time technology will have grown faster than legislation. Frankly, they are probably more concerned with a way to tax this than to stop it. Gambling has been going just as long as prostitution and a handful of other things deemed illegal. Taxation and regulation is the answer, not prohibition.
