I should have looked at the code first...

That's exactly what you need.. Set NETSNMP_CACHE_HINT_HANDLER_ARGS in your
cache flags, and the hint will contain the full set of arguments that handlers
normally get. Those are the structures you need to poke around in. I'm pretty
sure you can find the peer address in there somewhere, but I'm not sure about
the local address.
The easiest way to do that would be to have a different community string for
each address. Otherwise you are probably going to have to modify the libraries.
