ABSOlutely. If you can imagine friends out in the wild that want to get each other back for an evening out or whatever, maybe they can do it through their mobiles. My grandma has a smart phone and no computer... look at the demographics. If we assume that the more people that use and accept NEM the better, then we need to acknowledge the increasing demographic of mobile devices. Especially given mobile means on the move means spending money. Add in the "bump" feature of things like Android where I can just transfer you money with a bump and a swipe or something and the "tokens" gain value as a symbol of exchange, even if not directly tied to fiat. Meaning, folks might use them as "wooden nickels" to keep tabs of who got dinner last or whatever. That they could even be used in this fashion would give them value and support the network.

The bottom line is for a currency to actually be valuable it must be incredibly liquid. It must be highly accepted and easily exchanged so anything we do to that end whether its JSON/REST mobile APIs or QR codes the easier the better. This can't be understated. Even if it could be used as virtual currency (think Linden Dollars or money for an auction house in a game), it would gain value. These things are all easy to do if we properly create APIs for the targeted technology, and if we do a good job with grassroots adoption (maybe even viral in a game). Included in this is definitely gamification or similar.
