It was written to track down a series of bugs in the message passing part
of the IPC code - which don't care where the sockets came from. I did them
that way because it was easy ;-) This is by far the trickiest part.
But, it would be easy enough to put in a simple authorization test anyway...
verify that your peer's user id is the same as yours.
Verify that your peer's group id is the same as yours.
(this won't work with Andrew's authentication code)
I asked Andrew to add his authentication code to CVS. He said he'd try
and get to that Monday.
There is a better way to do this on Solaris (using streams), but no one has
written this code yet ;-).
