Are you familiar with the Android Account Manager? [1] You can let users log in to your app with pretty much one click of an existing account. Since virtually every android user already have a google account signed in on their phones. It seems that using a google account would be the most obvious route for ideal user experience (no need to type in a new account you haven't before).
That's funny, I'm the opposite. I'm generally unlikely to sign up for any site or service that makes me create and record yet another username/password combo.
It seems there's a discussion on your forum now. [1]
Unfortunately, to chime in on the discussion one needs to log in with Facebook, which might keep a good chunk of those 'Please support something else' voices out. I know you wrote (both here and in that entry) that you plan to support other authentication methods. The reason why I post this is just to point out the flaw of asking the subset that willingly gives out their FB details in the first place.
I use llama for Android, which is a free app where you can do these things. The drawback it has is that there you do not get to program your scenarios using javascript, you instead need to create them through a GUI on phone.
Can the browser/login be completely removed from the picture, so that you get to manage your own scenarios either online or at home computer and push some compiled file to the phone yourself?
