Or like the AmigaOS??? Note that user accesible IPC was made
somewhat standard on the Amiga via AREXX "ports". And the Amiga
OS is much faster than Windows.
The Hurd is also a project to give the user more freedom than
is given on traditional *nix type systems. More Freedom in the
User Space.
Using the analogy of dumb and smart terminal for this user space,
I would think it possible to make a smart user space interface.
This way the user gets the benefits of corner cutting speed and
when needed, the resources it can get thru the Hurd.
Sorta a trade off, where security and uncrashability of the
system overall is what the Target of the Hurd is, but the users
smart interface can still do alot itself while not infringing
upon that security and stability of the Hurd.
Between the smart and streamlined user interface and the Hurd,
you have IPC standardized (Finally??) to be Signal/Semiphore,
Message and Memory location(s).
Although the AmigaOS is proprietary, a portable clone project
is past 3/4 the way there. AROS on sourceforge.
