I know this of cource, but my thoughts on the possible merge was to look 
at what we could
need from msdosfs-30 and if we are done with it I want do take a look at 
msdosfs-48. That is
the current version from opendarwin which is also the current version 
from apple's website.

A friend of me is working on OpenDarwin and he said that apple didn't 
release any changelogs
and that is what it makes hard to see what has changed.

I also know that my hacking knowledge is very limited. I only had 
knowledge in general c programming
and a lot of time the next months. That was my attention. ;)
