I hadn't had my caffeine yet... you can do this by setting up contexts in the
snmpd.conf file access control. See the context discussion at
http://www.freesnmp.com/net-snmp/faqs/#multidev
So in each module's init routine, you just have to register each object/table
that will respond differently N times with N contexts, where N is the number of
interfaces.
Note that if you are using sub-agents for this, I believe 5.2.1 is required
(5.1.2 might work, I can't remember). Earlier releases didn't pass context info
to sub-agents...
