In the end though, as the interest for Bitcoin as a currency decreased, none of our users were interested to offer Bitcoin as a payment mechanism anymore. We've since put this experiment on the backburner. Happy to revisit whenever there is demand for it.
Regarding other non traditional payments methods (wire transfers, Boleto, etc.), this is absolutely supported and heavily used outside of NA.
Back in the days, we tried very hard to have a good native integration with the blockchain for recurring payments (see the "Extension for BIP-0070 to support recurring payments" thread on the bitcoin-dev list: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2014...). It didn't go anywhere unfortunately, so we added support for the major providers at the time (Bitpay, Coinbase, ... see http://killbill.io/blog/coinbase-integration-experiment/).
