I have a suggestion, but please don't take it the wrong way, I think it's 
great that someone is working on this kind of thing for KDE.

The Ethereal code base now has a nice separation between GUI and backend code, 
which would enable relatively simple creation of a KDE frontend for it.  I 
did start on such an effort a while back, but I have other priorities for my 
time at the moment.  I was planning to make it a kdevelop plugin, so you 
could analyse the network output of your program as you ran it.

Have you considered looking at Ethereal to see if it might be easier for you 
to integrate it into your program, rather than duplicating much of the 
ability that ethereal already has?

Cheers,
Hamish.
