Well (whisper whisper) the secret here is called Samba..

Wisper Wisper, It also has a little thing to do with ACL support on mounted filesystems.. Set up a samba share on a monuted file system in Linux without the ACL option seel how well it performs...

You have a point. Actually, Apple has to stretch here more than most because HFS+ didn't have much richer permissions structures than plain Unix does. I am sure this is what has kept OSX from offering complex ACL's till now.
