One more point of view:
Mac user and Zaurus (pdaXrom / weeXpc) user and developer here.
I regularly connect both devices via network (WLAN) and sync files using Chronosync on the Mac. This works just great.
However, I do not (yet) use the calendar or address book on the Mac, because I use those on the Zaurus (KO/PI and KA/PI under pdaXrom, not DTM) and am quite happy with them.
However, Once in a while I have the need to heavily edit the databases of both programs, which is cumbersome on the Zaurus due to its slower speed and smaller screen.
Also, sometimes when I'm working on the Mac I would like to just have access to the calendar or address book without looking for the Zaurus, switching it on and starting the PIMs.
So, I would very much like to sync KA/PI and KO/PI with the Mac in addition to the directories I sync now.
I would not necessarily need to sync with the Mac's built-in programs, if KO/PI and KA/PI would be available as Mac versions. I would then rather sync Kx/PI for Mac with Kx/PI on zaurus, which would probably work flawlessly.
Of course, it's possible to run KO/PI and KA/PI Windows versions on a Windows installation under Parallels under Mac OS, but that's again too cumbersome for my taste.
So these main questoins remain:
Did anyone attempt to compile KDEPIM/PI 2.2.7 on the Mac already?
Are there reliable solutions for syncing KDEPIM/PI with the Mac's calendar and address book?
