a VNC viewer that uses the D pad on the 770 to navigate around a full resolution screen on your home machine would at least give you the power of your home machine any ware in the house.

I just found this

NX Client Embedded Edition
Version: 1.2.2 for Sharp Zaurus 5xxx
http://www.nomachine.com/download_pr...php?Prod_Id=22

if it is made for the Zaurus the 770 should be doable for the 770. and if it works well I will buy it for my home machine.
