I would like to see an efficient ACL implementation to consider.

Unless you have a large user population with multiple domains of
administration the group concept is simpler and sufficient.  (A
group is just a ACL "macro".)  For my part, I like the tighter
security of P9 over *NIX.  If you have followed the list you will
notice I have tightened it further.  (I have effectively excluded
"none" from "other".)

Yes, but is it available in source and does it run on a PC? :->
