I don't think that's currently possible.

Wiretap is the "lowest module" - so you simply cannot (or better read: 
at least should not) call any of the preferences functionality. This 
will very certainly result in a circular dependency, as epan depends on 
wiretap and wiretap would depend on epan, which is not possible.


As you've noted, none of the other files in wiretap uses something like 
preferences, and it's probably a very good idea not to start it.

Reasonable defaults are your friend here ;-)
