Other than specifying the contents of a message in the new protocol to be easy to parse with a regexp tool, there's not much you can do about regular expressions in a protocol specification. I think that "messages should be regular in format and easy to parse" is a reasonable requirement, though. This might reflect into fixed-length fields, or labelled fields, in the protocol specification. Actual discussion of how to implement regexp or host allow/deny would seem to be a matter of, er, implementation, not protocol. Bob
