The main thing that bugs me about the current trusted UI is that we use it to 
load remote content, and content that is worth spoofing (since in the payment 
flow the user is asked for PIN & payment information).  So to the user it looks 
like it is part of the system, but in actual fact it is loading a remote web 
page.

I could be wrong, but if we have a way to shown the rocketbar in fullscreen,  
can't we ensure that the rocketbar is always shown when you swipe down from the 
top? And therefore have a way to ensure that the _real_ rocketbar is always 
shown. I guess what I'm hoping is that the "swipe from top of screen" gesture 
can be made unspoofable in the same way that a homescreen button is 
unspoofable. Not sure if this is actually possible though. Can this be done by 
catching gesture events somehow? Or could a fullscreen app intercept these 
events?
