You could always exchange for Liberty Reserve. It’s an online currency similar to e-Bullion, Pecunix or Webmoney that allows exchanges no questions asked and with privacy.
LR and the others are hard to buy but easy to cash out. Hard to buy because exchangers are very cautious about getting ripped off by reversed payments, so they require more details and holding time. Cashing out is very easy. LR is non-reversible, so there are oodles of exchanges eager to turn LR into any kind of payment.
Bitcoin is the reverse, in that it’s easy to get Bitcoins just by generating them. It would be easy for customers to go bitcoin->LR->cash, bitcoin->LR->gold, bitcoin->LR->paypal or maybe they just want to save the money, then just bitcoin->LR.
There’s also the idea BTC2PSC had to sell paysafecards for bitcoins. Either online delivery by sending the card number by e-mail, or delivery of the unopened physical card in the mails. There are many variations of these cards. In some countries, they’re called Gift Cards, and can be used wherever credit cards are accepted. I think they’re used more by people who don’t have the credit history to get a real credit card, so they buy gift cards themselves to pay for things that require a credit card.
