weston itself can be run directly as non-root inside an X session,
without use of weston-launch.  For client development or just kicking
the tires, this is probably sufficient as a starting point.  I imagine
many people who will be reading this document could fit into those
categories.

Certainly 'sudo make install' addresses the problem, however the intent
of the article as I read it is to show how to build wayland entirely
without needing superuser privs.  This is a worthwhile goal: It assures
tire kickers they won't muss up their system, it enables building,
installing, and testing wayland in automated test frameworks, and it
enables users to try out wayland who may not have superuser access.

Perhaps the documentation could first explain how to run non-root, and
then in a following section rebuild with setuid and explain running it
using weston-launch?
