Ah, okay. Now that's a different angle than the 'X for Y' device usually follows. I imagine you guys were shooting for the fewest words possible in deciding to go with the 'X for Y' approach as you did here. However, "X for Y" is a stylistic device that employs an analogy, and when the analogy is not based on the form or function of a thing, it gets easily confused.
Think of other products that use the 'X for Y' device--for example, a service that markets itself as 'Facebook for Sex'. The nearly automatic connection potential users are going to make is that this service is going to have certain obvious and well-known features of Facebook--like connecting with other users, building up a list of 'friends', etc. Now, if that service was, instead, a news feed of stories about sexual subjects, I think the users would be rightly confused by the analogy not being correct. Here, they'd have been better suited using the 'Facebook-like news feed for sexual content', or something more apt. The same could be said if the service was 'Google for Philosophy'--someone is going to automatically expect a philosophy search engine, not a pair of wearable eyeglasses that help you connect your everyday experiences to greater philosophical questions.
Perhaps you'd be better served with something along the lines of "Dropbox ease-of-use for WiFi passwords", or "Dropbox-style management of WiFi passwords". Here you're able to invoke the actual Dropbox feature your sample pool was connecting to that is not communicated clearly with the original wording.
Also, the only reason I think it's worth your attention is that you're actually having to explain the analogy multiple times to commenters here beside me. That's as strong an indication you can get that the analogy isn't working. You shouldn't ever have to explain what your marketing message means to your potential users.
Again, I think it's a great-looking product. Very well designed and executed, and the interaction simplicity is the real killer here (as you're obviously trying to communicate).
