There are more and more places where we are starting to need dissector 
routines in one dissector for a structure that is known about in another 
dissector. For example, in the Windows world, they seem to place a lot of 
their existing structures on the wire as blobs. Security descriptors seem 
to turn up all over the place.

Do we need a[nother] mechanism for registering and retrieving such 
dissectors?

Also, we might need some new coding guidelines because there are cases 
where some dissectors could almost be called from other dissectors, except 
that they should avoid modifying the COL_INFO column, for example.
