as you say, it's not clear to you i think!
try to think of the user applications
what would mean 'to export CPU' ? remote call functions? solved by Sun's RPC
and Java's RMI, and sevarl other; remote fork? MOSIX does it
a user app uses different APIs to talk to diferent kinds of devices; that's
why you need diferent drivers. If you don't want to change the applications;
you can't use a single driver for everything.
