A while back, Tony Thulborn wrote something similar (though not explicitly 
about arboreality).  From what I remember, it was something along the lines of 
the avian bodyplan arising via pedomorphosis.

Definitely.  What's more, there's an impressive array of small (and 
not-so-small) insectivorous, herbivorous, and omnivorous maniraptorans close to 
the origin of birds: alvarezsaurs, therizinosaurs, oviraptorosaurs (including 
_Incisivosaurus_ & _Protarchaeopteryx_), scansoriopterygids, possibly 
troodontids...  Among non-avian maniraptorans, the hypercarnivorous 
dromaeosaurids are starting to look like the exception, not the rule.
