I think we should focus on making Mintcoin stronger. Accentuate our positives while furthering development. Why should we be chasing down start ups asking them to add our coin? It should be the other way around. Coinkite is a start up.
https://bitpay.com/ is the current industry standard.
As I mentioned before, Vault of Satoshi is used by bitcoin atms for exchange purposes. If Mintcoin becomes popular enough, there is a possibility people will be able to access Mintcoin through atm in the future.
