sure.

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 
home-dir.

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.
