That was the idea.

Right now the global values are kind of scattered around the system and are
hard to find.  The enable checksum value spans node and internet stack and I
can think of reasons to put in both places.

In either case, you end up with a global variable that lifes in one place and
affects code in other places.  It seemed like a good idea to have a place to
put these things that worked with the rest of the system.  For example,
system-wide attributes would appear in the list of all attributes for easier
documentation.  Unless I'm mistaken, I don't think there is a list of all
global values anywhere in the documentation.

So, yes, the purpose of global values is to be global values.  I'm proposing
that we consider a set of system configuration attributes to take their place. 
It seems more organized and easier to deal with.
