Is the n770/n800 capable of connecting a USB2VGA adaptor to it's usb port?
The N800 has a usb 2.0 high-speed port, so there should at least be no usb-bandwith limit.

According to this site:
http://www.nslu2-linux.org/wiki/HowTo/AddVGAAdapter

There are also devices available that support linux...

Anybody an idea?
