I've just completed the first round of porting xjadeo to OSX.
On the way to learn about cross-OS video coding and prepare for sodankyla, I've added a native display (carbon/quicktime) and included a mac-style menu-bar to Jadeo instead of using remote-control and qjadeo. Far from perfect but usable, there's still performance improvements on the ToDo-list and surely a bug or two to fix ;)
expect a universal binary DMG and merge with sourceforge-SVN mid next week.
Amending: a DMG for testing is available from here; I've postponed further work until there's more feedback.
