I am researching a device that I can use for VNC that I can keep in my pocket and use just about anywhere. It looks like the N800 with the ability to access wifi or in a pinch my bluetooth phone, might work.

Here's the situation. I own a business which operates more than one store. The technical skill level of my employees is minimal. At each store I have a specialized point of sale system. With a laptop and tight VNC I can access the point of sale system and answer questions or fix problems that come up as well as monitor sales for the day. It happens occassionally that an "emergency" comes up when I'm not anywhere near a computer or laptop.

I'm thinking that with an N800 and my phone at a minimum I could connect to the store and see what is going on when an employee calls me in a panic.

How hard would it be to install tight VNC on this device? How well does it work? I've never used linux and haven't used any form of unix for several years.
