Quick question: have you thought about porting this to sandstorm.io? Having a one-click "app-like" install would help out many less-technical church folks.
Only our hosting service is in closed alpha. The source code is all open (https://github.com/sandstorm-io/sandstorm) and there's an easy installer script (though it requires a Linux machine), so you can start hacking any time. :)
I'm sure Kenton, who has commented eksewhere, can send you an invite.
Although targeted at churches, your application is essentially a mini as of isle network, and would thus be a very interesting test case for sandstorm.
