That sounds like a great idea.

I'm happy to advise / help out on anything that's unclear about the Perl
bindings - either on this list, or 'danpb' / 'danpb_ltop'  on the DBus
IRC channel.

Yep, I certainly won't claim the tutorials are complete ! They do presume
you know what the core dbus concepts are to a certain extent. And I only
really did the one for exporting objects

http://search.cpan.org/dist/Net-DBus/lib/Net/DBus/Tutorial/ExportingObjects.pod

and never got free time to do the corresponding client one for using
objects

http://search.cpan.org/dist/Net-DBus/lib/Net/DBus/Tutorial/UsingObjects.pod

If you want to have any of your docs included in the official Perl Net::DBus
releases I'm only to happy to accept patches for the docs / extra tutorials.
Either send them to this list, or to me directly & I'll apply them. The
master source repo I use is published

  http://hg.berrange.com/libraries/net-dbus--devel

Regards,
Dan.
