When an organization buys software, it usually buys the right to run
N copies of the software.  With "Hot Seat" licenses, these copies can
run on any nodes in the network, providing no more than N copies are
running at once.  The copies coordinate either with each other or with a
"License Server" (such as Apollos's NLS) in order to oversee the use of
the licenses.  In contrast, with node-locked licenses, the organization
licenses the software to run on N nodes.

Hot-seat licenses are a reflection of:

	1) The true nature of hardware reliability, in which nodes
           go down.  With hot-seat licenses, you can in general run 
	   the software on another node.

	2) The true nature of software use, in which users do not use
	   a piece of software 24hours per day, every day.  Hot seat
	   licenses allow different users to use the software at
	   different times, without the users having to share nodes.
	   In a large network, this is almost mandatory.

Node-locked licenses are a reflection of:

	1) The true nature of software technology, in which vendors
	   do not (did not???) want to develop the somewhat complex 
	   software necessary to coordinate multiple invocations of
	   their software.

	2) The true nature of software marketing, in which it is
	   clearly better to sell someone something that a) will
	   be unused most of the time, and b) you can sell them
	   several times as many of.
