We just launched ProbeBuilder, a fully automated custom SNMP probe builder/generator for InterMapper.

The site is now open for beta testing, fully functional, although a beta login is required in order to generate and check out probes.

On the technical side, everything was built from the group up using Java (JSTL, Servlets, etc.)

If you're using InterMapper and are interested in building probes, drop me a note, I'm pretty sure I can finagle a beta access code.
