yes - access - meaning rwx - but not changung the ACLs.
if user A and user B have access to files on one share - the ownerships 
will be mixed. so only the root will be the man who can change rights 
and there is no possibility to priviledge user A so that he is abled too.

correct - but if i would allow acces to my home-folder to other users - 
i would loose control over files, that other users created because they! 
and not me would be abled to change the ACLs of their files within my

quota doesn't matter.

the point is: POSIX ACLs are crap (compared to Novell and NTFS) - 
because they only allow RWX. Taking ownership is the only way to be 
abled to change the ACL of a file as a normal user.
But normal users cannot take ownerships of files they don't own. So the 
POSIX-ACLs are still unusable for situations where users should be 
priviledged to change ACLs within a folder where many people have access.
