Is there a way to pull down nessus to a RHEL server you're SSH'ed into?

I'm ssh'ed into a server i cant go to right now and it's running RHEL5. Im connected as root. I want to download Nessus server demo. there doesnt seem to be a way to do that through my google searches. So far it looks like i have to download the RPM and walk it to the device on a flash drive then install it from GUI.
