mathematical modeling of linguistic contact/diffusion

[Richard J Senghas]

A mathematician friend of mine has approached me about exploring the 
possibilities of doing some modelling of language contact/diffusion, 
especially with regard to the language I focus on (Nicaraguan Sign 
Language).  Has anyone on this list been involved in language 
modelling?  I'd be interested in hearing about the experience.  Feel 
free to post responses to the list, since those of us who haven't 
done much modelling could probably do with some exposure to the 
topic, even if we don't hold with it.  In fact, it may be useful to 
see what issues or criticisms might be worth addressing if we get to 
the point of pursuing this in earnest, especially if we consider how 
to write it up for linguistic anthropologists or other "non-math" 
folk.

I'd also love to hear about articles and other publications about 
modelling that are targeted for non-mathematical audiences, 
especially social science researchers.
