  Sounds good.

  OK... my main surprise is that you've re-written a RADIUS
encoder/decoder, and a dictioanry file parser.  All of that code already
exists...

  The "radsniff" program distributed with FreeRADIUS reads PCAP files.
It uses the FreeRADIUS library to read the dictionaries, and the library
can send/receive packets.

  It may have been less work to glue some "send/receive" logic into
radsniff.

  Still, the tool looks useful.
