Here's some ideas of what an "open system" is from the book "Building An
Open System" by Slonim, et al.

	"In the context of computer systems, open systems are those
	 characterized by flows of data across boundaries between autonomous
	 systems."

	"Therefore, in this context (ISO/OSI), 'open system' will refer to a
	 computer organized and operated in such a way that it can be easily
	 connected to other independently organized and operated systems
	 through telecommunication links in order to exchange data on an
	 as-needed basis."

"What makes a system 'open'?" Technologically, it involves a lot of issues
that the discussion will be very long (and I'm not well qualified), so I'll
skip it here.  But in general, it involves communications, operating
systems, databases, languages, etc.
