I just add my two cents, on�
http://sourceforge.net/projects/z-tools/�you can find all Zorro's work in up-to-date state (i.e. cleaned Makefiles, fixed compilation issues etc), plan is to make all stuff shareable (all his products just use copy&pasted code, I cleaned up some things but still not everything, especially in zView) so zDesk would gain from this structure as well.
