If you axe write support, does the maintainability of the kernel ntfs get 
easier?  As I understand it, the write support is rather limited, and 
debugging and fixing read support is generally a lot easier for a variety of 
reasons.  There's also a lot less risk to data. :-)  I think it's reasonable 
to surmise that, given our rather limited write support currently, the kernel 
ntfs code is used for data migration and limited sharing to FreeBSD in various 
forms, but that msdofs remains the general data transport of choice...
