 Plan 9 makes it easy via 9p, its file system/resource sharing
protocol. In plan 9, things like graphics and network drivers export a
9p interface (a filetree). Furthermore, 9p is network transparent
which means accesses to remote resources look exactly like accesses to
local resources, and this is the main trick - processes do not care
whether the file they are interested in is being served by the kernel,
a userspace process, or a machine half way across the world.
