| Pipes should work just fine with icons. Better, even. You should just be able

| Why? What are your reasons for deciding pipes are insufficient. What

+---------------

I think he means he'd like to see a new socket domain which passes packets
which would be the equivalent of Macintosh resources (which are what are
stored in the clipboard and the scrapbook and even on the system heap, as
well as in the resource forks of files).  The best one can do with pipes
is implement the equivalent of MacBinary protocol on top of them, which is
doable but slows things down and makes the code bigger.  Besides, if one
puts them in the kernel then one can assign *and check* user/group IDs and
permissions on resources, allowing programs to pass resources around that
they can't access but *can* pass on to something else that can access them,
without producing a security problem.
