Alright, so we've already got a system that allows people to "gift" subscriptions to eachother, one-time payments that end up as credit on the recipients account. Would it be entirely infeasible to set it up so that people can do this using paypal and similar "one-time" payment services, and also combine this with the ability to Only use your "credit" to finance your subscription, removing the need to fill out card info etc? I think this solution would be a workable middle-ground for those who live in countries with expensive prepaid cards and who can not, or do not want to, get a credit/debit card.
