Or "media_type".  Have Wiretap supply a media type string for a 
WTAP_ENCAP_MEDIA encapsulation.  (Of course, that won't work for files 
whose contents *don't* have a media type - but given that KDE and 
GNOME, at least, tend to use media types as file types, I suspect file 
types that don't have official media types will be given media types by 
the UNIX+X desktop folks.  I also suspect that most of the media 
dissectors will be for data with media types, as they'll probably 
mostly be written for use when dissecting HTTP and the like.)
