That is a really interesting concept. 

What I think would be really neat would be a NEMshift. Basically some kind exchange/plugin/app that could be used to spend NEM at any place that accepts bitcoin.  This would be a really cool project for Altnemo I think.  I would love to see Paypal accept BItcoin and then NEM be able to plug-in to Paypal via a NEMshift.  I have no idea how it could be done, but I think it would be a really cool project for Altnemo. 

What we really need is stores and ATMs that deal in NEM directly, but something like a NEMshift would be a good stopgap.
