Hello,

for a proprietary protocol based on the OSI-stack I would like to 
write a plugin. I am forced to do so, because we got information about 
the protocol under NDA.

After playing around with the gryphon-example I have some questions:
1. In COTP there is no additional separator like the port-number in 
   TCP. Can a plugin create a filter at registration to look into the
   first few bytes of the remaining data of the frame?
2. In the current ABI for plugins the dissector doesn't return a value.
   I think it could be useful to return a boolean with information 
   about sucessful decoding. It would enable the installation of 
   multiple plugins basing ontop of COTP and is a possible solution 
   to my first question. What do you think?
3. It seems, that I cannot apply a display filter for a plugin.
   A display filter "XYZ" for a plugin registred as protocol "XYZ" 
   didn't work for me. Bug in my code or plugin design issue?

  Gerrit

Btw: Gerald, thanks for the CVS-tarballs.
