Remote Rendering

Hello Everyone.

Since my desktop computer is rather slow, I was able to gain access to a cluster that a friend of mine is an administrator of. I do not have root access, but I installed yafray into my home dir, and it seems to work fine. What I would like to do is have Blender export my scene to yafray’s xml notation, render it on a remote server, and then give me the rendered image back on my desktop. Does anyone know of software that allows me to do this? I know I could write a plugin, but I am lazy and would rather not reinvent the wheel if at all possible.

I should mention that I am not looking for a daemon program to run on the server. I don’t have access to the privileges that I need to have a daemon running, listening to external ports (firewalled, to some extent).
