I know Richard was thinking about this a few years ago 
(http://www.ethereal.com/lists/ethereal-dev/199907/msg00129.html).  What 
ever happened to the "6000 lines of code", Richard?  IIRC you built the 
SMB stuff with this PDL.

Analyzer (http://analyzer.polito.it/) and Spy have protocol or  rather 
packet description languages.  We mentioned spy's 
(http://pweb.de.uu.net/trillian.of/Spy/documentation/doc4.html#4) in the 
earlier discussion.  Analyzer has a BSD type license and SPY seems to be 
proprietary.  It would be nice to find a GPL packet description language 
we could incorporate.
