Hi Thomas,
If I remember correctly*, there is a method of forcing the D-BUS server and client to use TCP over the loopback interface for various purposes.
When I was interested in working with IPC systems, about a year ago, I managed to build a reasonably large library of trace files that way (although I can't locate any at the moment), and I would have been interested in a D-BUS dissector for Wireshark.
* According to the manual page for the D-BUS Daemon , adding
<listen>tcp:host=localhost,port=1234</listen> to one of the D-BUS configuration files, substituting
1234 in the example for your chosen port number should enable you for handling traffic via TCP.
I hope that helps.
Tyson.
