F7, SELinux, and security

[Beartooth]

	Picked out of the getting rid of SELinux thread on this list, 
originated by me, and now made a thread of its own, also by me -- 
because, while still as interesting as ever, especially to me, it has 
broadened enough that people seeking help specifically with SELinux would 
be apt to overlook it. (Or at least I would.)

	Since the context (I think) involves LANs and suchlike things, 
you must mean "physically next," not just electronically via the Net, 
right? 

	Iow, if I run some app that discovers malware on linux boxes, and 
find some on one of the machines on my desk, it will more likely have 
come from one of my others that off the Net or the Web, right?

	But surely that machine here, or some machine here, got it in the 
first place electronically?

	I seem to be getting more confused than usual here ....
