The problem is that the Mac MB client may be incompatible with the PC MB server, and they\'d have to change the server to a version where some problems were fixed.
I understand that the endianness issues have been worked out of CB, and so when CB comes along, we the Mac community will be able to supply the devs with a working build & installer.
Also worth noting is that the performance problems were fixed prior to Panther; current CrystalSpace on 10.2.8 works fine.
