Just to let everyone know, a few days I launched a new venture ZappMarket, which is a facebook app for selling of Android applications. There area dozen different payments options, including an offer wall for those users who are unable to use paypal credit cards. You can even use Zong to make a mobile payment. Basically, this will reach anyone, anywhere provided they have a facebook account.
There are already two good apps up there: Attack Breaker and Speed Forge. I'm putting out a general call for additional paid applications (ZappMarket does not accept free apps).
