Now that "Pebble smart-watch" has its own AppStore inside Apple's one, would it be possible to code a simple wallet there? Maybe that would allow to byPass Apple restrictions, since all is done between the own watch and the iOS Pebble app
In addition, I think that all the Pebble apps are compatible with both Android and iOS, since code is executed by the watch...
Just read the Google Glasses topic, and although it wouldn't be the same (Pebble has no camera), maybe someone could try something there (I've not idea of the programming language used on it)
I'm thinking about a simple wallet from where you were able to sign transactions or something, or cold storage BTC, who knows... Maybe just confirm transactions before sending them... I've just started to think about it
