Yes.

The CLEANUP calls should be necessary only if there's a tvbuff routine, 
or a dissector, called between the CLEANUP_PUSH and 
CLEANUP_CALL_AND_POP routines, so that an exception might be thrown by 
the code between them; it doesn't look as if that code could throw an 
exception, however, so it should just be sufficient to do 
"g_free(md5_buff)" after the loop exits, and not bother with the 
CLEANUP calls.

Well, the first hint is that we don't have any mechanism for attaching 
data, via the GUI, to a conversation, so you'd have to implement that 
mechanism, first.

You might want to use code similar to what's used for the global 
preferences, so that a dissector would just register a set of 
per-conversation settings, and common GUI code would be used to let the 
user set them - a dissector can't itself have any GUI code, as it would 
have to work in Tethereal as well.
