Neat! That could be very useful for everything that works well within the limitations of vnc.
Edit: I've tried this out! I loosely followed the guide on a Kindle Fire and I'm much more impressed with the results than I thought I would be. No Libreoffice in the default repository, but I'm impressed with the responsiveness while running Abiword in XFCE4. Initial impression is that the app selection is hit or miss relative to running full-bore linux on a desktop computer, but I'm still experimenting. Firefox installs and I was surprised to see that youtube videos were playable to an extent. Much less laggy than trying to run vnc between two separate devices. I'll probably keep this setup if for no other reason than to have a desktop version of firefox on my tablet.
