Validation of the protocol fields (like checksums) can be done without
external input and would be nice. On violation, these could add "expert
info" to the tree.

But for Authorization digests in SIP, this would require external input
(credentials), possibly through a preference (filename or UAT). I think
it is better as separate script (since the input format can be different
depending on the user), but wouldn't object if a patch is proposed.

802.11 and SSL decryption also require external input, so it's not as if we don't do anything requiring external input.
