On most if not all UN*Xes, the executable image's code and read-only data, and libwireshark's/libwiretap's/libwsutil's code and read-only data, should be shared between all of the processes.

You won't, however, share the results of reading in configuration files, e.g. the new fields added by reading in the RADIUS and DIAMETER dictionaries...

...unless they're read in by the UI process, and handed to the dissector processes as (read-only) shared memory.

I *think* Windows DLLs may also function as shared libraries.
