Please don't take this personally Marc, but I think your objections
wound up proving my point . . .

Ignoring the net is ignoring part of the cost of support. Forbidding
customization does cut support costs, but is exactly what centralized
computing systems do to cut support costs. Customization and hetero-
geneity are touted as virtues of distributed computing. MIT has
correctly determined that they increase support costs, and chose to
give up that benefit for the sake of lower costs. Don't get me wrong,
I agree with MIT.
And if memory serves, doesn't MIT run large chunks of the project
athena stuff? Did the development cost of that get factored into
support.

It's easy to support the "easy" 95% of users. It's the 5% that needs
(demands) customization, that needs special machines, etc, that increases
the costs.
