Many, many years ago, I wrote a fairly minimal SNMP agent in Ruby
(http://theshed.hezmatt.org/rubysnmpd/index.html), which was
explicitly designed to be easily extensible (it didn't do anything useful by
itself).  If your team's into Ruby, that might be a possibility.

Otherwise, net-snmp does come with some fairly decent extensibility
capabilities these days.  It has a variety of mechanisms by which you can
feed extra data into it, and in general I'd recommend going down that route.
