Yes. Important in a dual booting enviroment.

I would If I had the needed knowledge in FS and Kernel. I only have
availability to offer.

Yes: Speed.
A year ago when building my zfs box I had to migrate 500GB of data off
NTFS. FUSE ntfs is WAY slow. I didn't do a proper benchmark then but I
could setup something now if interest arises.
I didn't have any problems like those being reported with CURRENT from
April 2007 if I recall the date correctly when I copied all that data.

Yes if...

Yes if FUSE ntfs can have performance on par with the current ntfs support.
Yes if FUSE ntfs license model doesn't become an issue.
Yes because FUSE ntfs write support is neat =)
