I know it's not the same, but I've connected a T68 to a laptop via TightVnc and bvnc. I only used it to write and edit text. It worked. But it was too slow to be useful. And that was just editing text. Oddly, Windows notepad worked faster than other text processing programs. Don't know why. But it was still too slow. Hopefully later iterations of Onyx devices will have less latency. Also perhaps one can reduce latency in your wifi environment. But when you think about it, going via wifi is never going to be the fastest. Bluetooth or a USB connection will be faster.

I tested a Bluetooth keyboard with the T68 and that was perfectly usable. Again I only tested text processing. There is a video on a couple of videos on youtube of the same setup with a Kepler Pro, and the latency is pretty similar.

So I would guess that with the Onyx devices, you'd be better running a bluetooth set up. Develop your code or whatever on the ereader, then copy it to your computer. Probably the best solution to edit text on the ereader is with vimtouch.

In my experience on a T68, a wifi secondary monitor is too slow. But maybe the newer Onyx's are faster.

Edit: apparently the new Onyx comes with HDMI connectivity. It's a game-changer if the ereader can be connected directly to a pc via a cable. That would be fast. But current Onyx's don't have the ability to connect directly.
