The issue that might arise of course is that Flash content by nature is very flexible and there will be very different things that people think are important to track. A button that moves some content 10px to the left might be uninportant for one person to track while it is the most important thing for another person.

A standard should perhaps thus concentrate on outlining a few defined metrics so that one can more easily compare different sites based on these metrics. Try to find the things that are generic to most flash sites and build metrics around those first.

Whether or not I’d be willing to use a separate application for viewing these metrics really depends on what additional value I can get from it. So perhaps the second task before you jump into coding would be to do a more specific list on what the features of such an application would be?
