It depends I think how much money, how often and in exchange for what. If you are paying out big amounts in exchange for "labor" (e.g. paying freelancers who do work for other users), checks, ACH, and wire are the only serious solutions unfortunately. For smaller amounts and gift/bonus type payments, you might be able to use electronic gift cards (e.g. Amazon)-- if I recall, you only need an email address and possibly name to send a "gift card" this way.
