Now we have some parallel port scanners supported by
sane and I get several messages with questions how
the people can access their scanner as user.

We need a better way to handle these scanners.
It really is dangerous to run the frontends as
root or with suid=root.

So I want to ask all authors of backends that support
parallel port scanners to work out a common way
(sanei_parallel_*) to talk as user to the scanner.
These sanei_parallel_* routines should run on
as much systems as possible (not only linux!).

Please also add a text to the manpage of the
backend how the scanner can be used by user
and also point out how dangerous it is with

An other way would be to connect via sane-net/saned
to the local machine but as far as I tested that
still does not work very well due to a bug in sane-net
or saned.
