[SNMP4J] developing an SNMP agent

[Frank Fock]

Daniel,

I hope to be able to release an alpha version of SNMP4J-Agent end
of March. A MIB compiler like AgenPro, Mibble, or SMI4J will then
be helpful to generate stubs (Mibble and SMI4J will need to provide
support for the SNMP4J stub interface first, of course).

Best regards,
Frank
