What would be nice would be a language to describe a packet format and 
an interpreter for the language, so that a non-programmer could add a 
dissector for simpler protocols.  Even if you just know that there's a 
34-byte header, and don't know its contents, you could describe the 
header as a 34-byte opaque blob.
