Don't know about Michael Labriola's work, but in the Falcon JS demo at
FlexSummit someone said that the size of the generated JavaScript code
is a total of 5mb for a simple app with a few buttons. That can be
reduced to 2.5 mb using Google Closure compiler, but 2.5 mb of JS is
still A LOT of JS code for a simple app. OpenLaszlo generates 600kb
without using Google Closure's optimization for a simple app, and the
largest apps I'm aware of with 110k+ lines of "MXML" like code will
generate into 1.8-1.9 mb of JS code with the platform.

Without knowing the details of Falcon JS it's hard to know why the
file size is so much larger with Falcon JS. I doubt that the iPad
renders a 2.5 mb JS app with a good performance (the problem is JS
parsing, not execution of the code).
