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. Regards. Lars Roland
