Support for Crypto Currencies
Support for cryptocurrencies would be much appreciative like the upcoming mysterium network (decentralized vpn system due out this quarter). They have a built in payment system so you wouldn't need to build much yourself to integrate it into your network. They are open to large vpn services collaborating with them.

you don't need third party for such integration. Your existing infrastructure is enough, you just need additional payment option.
Я за интеграцию.
