Changing Remote Control Timeout for all clients

Hi, I read two documents( http://community.landesk.com/support/docs/DOC-1597 and http://community.landesk.com/support/docs/DOC-1391 ) about how to set the registry key on the client for changing the timeout, but I want to change the value for everyone, without having to manually change the value on every machine. The ten minute default timeout is not long enough for me so I would like to extend it, but whats the easiest way for me to do this?

Thanks
