Thank you for response. I know what you mean, it is currently very limited, functionality wise. I thought to just put it out there, and see what the response will be. In that way we can add new features for which we know is demand for.
Your suggestion of SMS is definitely something worth looking into. It is something we already considered to add. We are also looking into using push notifications, but SMS is something that always works even without 3g. Accepting payments in bitcoins is also a good idea.
Anyway we will be frequently adding new features. I will post them on this topic as soon as their added.
Oh yeah, the current crash really sucks. I heard that btc china is being blocked for incoming funds...
