Thanks, both of you, %Import was what I was searching for. After some minor 
modifications I was able to get sip run error-free. Compilation and linking 
also worked, but it seems I am missing a library somewhere. The commands I am 
using:

sip -I /usr/share/sip/qt -t Qt_3_2_0 -t WS_X11 -c td_sip tokendisplay.sip
g++ -c -Wall -o libTokenDisplayc.o -I /usr/include/python2.2 -I /usr/qt/3/
include -I td_sip -I . td_sip/TokenDisplaycmodule.cpp
g++ -shared -o libTokenDisplayc.so -L /usr/lib/python2.2/site-packages -l 
qtcmodule -L /usr/qt/3/lib -l qt-mt libTokenDisplayc.o

When i try to import the module in python i get the following:
>>> import TokenDisplay
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "TokenDisplay.py", line 8, in ?
    import libTokenDisplayc
ImportError: ./libTokenDisplayc.so: undefined symbol: 
_ZTV20sipProxyTokenDisplay

nm libTokenDisplayc.so | grep sipProxyTokenDisplay gives
000014b4 T _ZN20sipProxyTokenDisplay12getProxySlotEPc
000014d6 T _ZN20sipProxyTokenDisplay9proxySlotEN12TokenDisplay11MouseButtonEj
000015ea T _ZN20sipProxyTokenDisplay9proxySlotEP7QObject
00001560 T _ZN20sipProxyTokenDisplay9proxySlotEii
00001684 T _ZN20sipProxyTokenDisplay9proxySlotEv
000018e2 W _ZN20sipProxyTokenDisplayC1Ev
         U _ZTV20sipProxyTokenDisplay
00002d7c d _ZZN20sipProxyTokenDisplay12getProxySlotEPcE3tab

Neither libqtcmodule.so nor libsip.so contain this symbol either.
Any clue what's wrong here?

TIA,
Jan
