i've got about 3000 machines sitting around the streets of Germany and i'd
like to deploy some software from
our server onto each of these machines, without walking around to each of
them. i need to install it and get it running.
i do not have the luxury of preinstalling any RSH daemons or such like on
the target hosts

can anybody suggest how this would be done?

i have admin rights and can install any tools i like on the server.
