Is any support planned for 10.4?
Apple totally changed the kernel interfaces in 10.4 and a lot of work will be needed to get the driver running -- and I don't have the time right now to do much.
Could you just give an idea of by when will you have time to implement Tiger version? Is it possible to increase your time devoted to this task with donations?
I really don't have any idea. My paying job is keeping me busy enough as is, and I just don't have the will to work on ext2fs now (I personally do not use Linux that much anymore).
I hate to take donations, as I can't promise anything. Plus if we were take my normal consulting fee of $125 US per hr. and multiply it by the expected man hours of 80-160 that's $10-20K US -- which I doubt could be raised. And finally, I do not want to be responsible for managing a donation account (with escrow and everything).
