[e2e] simulation, sanity, citation, and storage

[David P. Reed]

Jon - really good main point.   But is deciding when to start and stop a 
simulation the criteria for a realistic model?

Sounds to me like saying we should assume everything is gaussian for the 
sake of simplifying the math.

I don't know what a good mobility model would be, but I really suspect 
that mobility in rush hour is not at all like mobility on Friday 
afternoon before a long weekend, just as one example.    And NEITHER is 
a distribution I would expect to be either uniform or stationary.
