That sounds interesting.

A case that I ran into was that I needed to call the KRB5 dissector from 
withing SPNEGO, but I did not want the KRB5 dissector upsetting the 
COL_INFO field so I added a flag.

However, perhaps what I really want is some fancy text in the COL_INFO 
field that is determined by the caller of the KRB5 dissector.
