Well, not quite, there are a few barriers:
 - You need to authenticate into the host.  Depending on the provider,
this is either done by providing a password, an ssh key, or receiving
a password after booting, or as Ian mentioned, via an existing ssh
 - You would need to install runurl, this most likely means either
just SCPing it up, but you'll still want to use apt or yum or X to
install curl or wget etc.
