Subject: Category Theory and Hereditarily-Finite Sets

Hello Cat Theory Community,
Hereditarily-finite sets are becoming increasingly more popular in
computer science research.
1) What kind of interesting categories exist where an
"object" is a hereditarily-finite set plus some
structure on the set and a "morphism" would be a
structure-preserving function. (I can think
of the obvious subcategory of SET and also the
category where an object is a hereditarily-finite
set together with a "SET" endomorphism on that
set, but neither of these categories would have
interesting or useful properties, in my opinion)
2) What kind of papers can I read on this subject?
Regards,
Bill Halchin
