deadhorse.
i'll risk repeating skip because you seem to have missed his point.
sharing REQUIRES trust!
if you use plan 9, linux, windows, osx, vms or whatever you
trust that the authors haven't trojaned the os. if you use a
pc, a mac, a vax 11/780, an ipaq or whatever, you trust that
the hardware guys don't have something in there working
against your interest. (if you've seen what intel's put in their
"desktop" proe/1000 chips lately, ironicly in the name of
security, you'd have an inkling of how this might happen.)
you trust your network provider not to send 20KV down the
wire, etc.
i don't think anyone here advocates sharing needles.
on the other hand, wearing a full-body condom to sleep
by oneself is a bit silly.
but suppose you do. then watch out for the junkies. they might just
poke you in the butt right through that full-body condom.
