The image of someone using CQC though the 770 was someone you was using RDesktop on the 770 to connect to a PC running Remote Desktop. This is really slick. I've installed RDesktop on my 770 and it works really well. I know Jay was using a VNC client on his to do something similar. At this point I'm personnaly leaning towards using RDesktop.
A few other thoughts I've had about the device. The newer version of the device, has a newer version of the OS. There is a mozilla based browser and an updated version of flash for it. This OS is not officially supported on the 770, but you can download the "hacker edition" of the OS for the 770, from Nokia. So it may be possible to upgrade the browser.
Anyway I'm still rebuilding/re-designing most of my HA computer infrastructure after some hardware issues left the previous incarnation too unstable. So I haven't gotten to try all of these theories tested yet. I'd love to hear others experiences.
