I assume you will be developing one, but when?
I direly miss a Mac client that would be both Tiger (MacOS 10.4) and Leopard (MacOS 10.5) compatible, since, as many users and families, i have a local network with data from different Macs to sync, and OrbitFiles would be great on them.
[Many Mac users still have at least one older, non Intel Mac: Mac OS being very innovative, Macs tend to be usable for online and offline activities quite longer than PCs… and Leopard is almost only useful on Intel Macs.]
Keep up the good work!
