It actually looks like it's on the right track. After doing some minor testing, it's a little bit buggy.
When you commit a take record, it disappears from the iphone layout. It will show up in the other layouts, but the take number gets lost.
The ability to quickly add a camera is missing.
Also, the "Work Done" (VFX Work) field is missing.
These are just some minor tweaks that could get this Layout up and running.
I do think it could work really well for someone, like me, who uses an iTouch rather than an iPod.
