I have not looked in detail at the specifics of each of the vo's that
have this problem so I have to believe that you are right.  I have no
reason not to.  :-)

There are a couple of ways to handle this problem though.  One is
POSIX capabilities (if such devices are protected by capabilities) and
the other is "pam-console".  The latter sets ownership of devices that
should only be accessed by the user at the console to his uid
(keyboard, mouse, video out, cd-rom, etc.).

Well, the argument could be made that a user at the console of a
workstation should have ownership and access to the input/output
hardware of the worksation.

Indeed.  I did.  I have not ventured enough to do the pam-console work
to make this work yet, but I also don't use a "root-needed" vo or ao's
that my distro does not already bestow the workstation user's
ownership upon.  I do have a Radeon and I suppose I could use vidix
with it, but Xvideo seems to work well enough with it.
