Hi David, the development of PyKdump is done using http://sourceforge.net/projects/pykdump/ but I did not push GUI yet as I played with several different approaches and was not sure the code is good for release yet (the server part is already in PyKdump git-repository, the 'devel' branch). At this moment the GUI client has some hard-wired pieces (links into HP-hosted server with unpacked kernel sources) so it needs a cleanup before you can use it. I'll send you the sources later this week so you could try GUI and provide your comments. I find Python-Qt more suitable for rapid development than C++ (and it more portable). But this really does not matter at this moment - it is more important to understand what benefits (compared to plain command-line crash) GUI can provide. Yes, it would be great if we could work on this together!
