Maybe I should read all the modelling messages before I comment on one.....

This is exactly right. I think the key here is in what we are trying to
formalise. Formalising the description of agent behaviour and environment and
then expecting to be able to prove great and wonderous things about their
behaviour when thrown together in a big simulation is beyond the scope of
anything I could presently hope to do.
However, creating a differential equation model of some global behaviour of a
Swarm simulation in a similar way to Mathematical biologists have always done
for reality is an extremely useful formalism (I know this is probably a
controversial view here). This formalism would allow analysis but it does
suffer
from the old problem of no longer being derived exactly from the agent
descriptions.
Add me to the Mumford reference list too please!
