I use an application called VNC which is a remote desktop tool - it gives you an X window view of the remote machine and it works on several platforms. www.vnc.com is where I got it from but the site has been updated so my old link doesnt work but have a llok there or http://sourceforge.net/projects/vnc-tight/ may be of use. You should be able to set them up to work over ssl and grid compute from the bath - but dont forget to run your laptop on batteries!
