Ok thanks - as you say we already provide this possibility so it would
be easy to move it to Debian - I was just not aware if it was a
acceptable solution, to provide 3rd party updating software. But I
guess that it will not be a problem as long as this updating software
does not make it impossible to uninstall the Debian package.
