>>4 It's an inside thing, I wouldn't be advertising the app anywhere other than here. Also people will be able to take pictures and share them, but it won't be a necessity. Similar to snapchat, they'd only exist for a limited amount of time.
It's a little early to think about this, but I wasn't even going to put it up on any app stores. (At least not major ones). Of course, that means that it wouldn't be tested by Apple or Google, but it's going to be an open source project and hopefully some fellow dollars will collaborate and therefore boost the integrity/authenticity of it. That's as I said, not a concern for the moment.
