Wow, it does not work? Apparently UNIX is completely broken. And ACL's are so complicated and a drain on performance as to be nearly useless - which is why they are not used much.
Shell scripts are where this is the biggest problem. I do shell scripting for a living and don't see this issue as being anywhere near as big a problem as Mr. Wheeler thinks it is.
Also, I'm completely confused by your title. I suggest conventions and then you suggest, perhaps facetiously, FAT (which is not a convention, but enforcement of a very stupidly limited set of possible filenames).
