Excellent little script. I have been using a hacked jumble of scripts to use my home server over a ssh tunnel and vnc. This is much more efficient for my uses and tons snappier than sending raw X displays over to my tablet. Although I do not have a good screen keyboard option to enter text, I do find it useful for remote and home stuff. Some fun and useful things I've done with it:

• Send xsane over to the tablet to acquire images from a networked scanner.
• Used scan2pdf to assemble a document and drop it on my tabler via sshfs
• Print openoffice docs off my tablet (by using snx to use my server to open docs on my tabler via a sshfs mount
• Ran VirtualBox with winxp and sent the display over to the tablet (this was for fun but actually worked quite well)
• Ran picasa3 via wine on the tablet and sorted photos.
