Well, it's only a hack for the moment :)

I did this lib because I wanted to use qpe developping tools (ui
and makefile generators) which prevented me from linking to, say,
packet-*.o. So I built a library to gather them :
ar r libzethereal.a packet-*.o afn.o asn1.o column.o conditions.o
capture_stop_conditions.o follow.o in_cksum.o ipproto.o pcap-util.o
prefs.o print.o ps.o ptvcursor.o reassemble.o ringbuffer.o util.o xdlc.o
xmlstub.o register.o
>From the experience I acquired developping zethereal, I see some points

of wishlist during my experiments, emphasing on what prevented me to do
things quickly.
Don't misunderstand me, the list that follow only focus on problems.
Ethereal is really a great project :)
- put every packet-*.c sources in their own directory !
- make a libpacket from packet-*.o
- lot of code about packet capture is generic but is not made available.
A direct consequence is that it is duplicated between ethereal
and tethereal.
An indirect consequence is that it is also duplicated in zethereal.
(if tethereal did not have a main, I could have linked to thetereal.o)
- The simultaneous use of wiretap and libpcap does not help clarity.
There are callbacks, callback wrappers, and so on..
- Lot's of functions seems to be integrated into the UI, like "follow tcp
stream", or masking packet in the UI (I may be wrong)
The abstract is : it lacks a clean API between core functions and UI.
Anyway, don't hesitate to look at the source
(http://www.cartel-securite.fr/pbiondi/zaurus/). It is very short.
