i've reading this maillist archives and see long discussion about ACL
implementing.

PLEASE DO NOT DO IT! it's not an argument that it's needed "because it
will make easier to use both windoze and netbsd in the same network".

if you like system that implement everything new and trying to
complement (or to compete with) windoze or keeping on with all new
commercial features it's already done. 

it's name is linux!

and it's the reason why i moved to netbsd.

i found old ideas in UNIX very functional, smart and simple in the same
time. file access permission system is excellent and no need to change.

please make already good UNIX better even more instead of bloating with
"very much needed features".

making netbsd popular OS is important, but making it good, smart and
proffesional (in good meaning) is far more important.

popularity != quality.
