file access

[shawn%mit-dspg at BRL.ARPA]

It seems to me that there should be some way to make it such that
a user program could not read a 'directory file', that his program
would use a 'system call' to read the 'next' entry in this directory
file if the protection permitted, it seems this would make the file
system in general more secure, or did I miss something? Oh, yes,
I am aware, that if this was ever done, the 'world' would break, but
that's a small price to pay for security, or is it?
