+
+- convert the code to do caching in buffer cache indexed by
+ file-vnode/file-offset so that NTFS would take advantage of UBC;
+ it should also improve performance somewhat, because if it's necessary
+ to find some offset in a file, it's possible to check if the data
+ are available in the cache before doing the bmap operation first
+ (from Chuq)
+
+- working VOP_BALLOC() (new in UBC)
+ (from Chuq)
+
+- readdir: evalutate impact of using variable length reclen - should
+ enable us to store much more entries into buf in typical case with
+ short filenames, though more work would need to be done in offset != 0
+ case
+
+- readdir: fill in proper "inode" number for '..' entry
+
+- handle Unicode filenames more inteligently - they are translated to UTF-2
+ form currently, adding hooks for various character sets or other encodings
+ would be trivial
+
+- implement writing into resident attributes, so it would be possible
+ to write into "small" files (<30KB) too
+ (from Semen Ustimenko <semenu@FreeBSD.org>)
+ generally, better write support
+
+
+- support mount update
+
+- really implement sync
+
+- write necessary bits to support NTFS in libsa
+
+- basic sysinst support for NTFS
+
+- NTFS ACL support (though usefullness of such feature is arguable)
