I've seen VNC server apps on the Google Playstore. Do they work? If so, what does it require to run them on U3s and Android TV boxes?

I did look at this http://www.tightvnc.com/ but that was as far as I got. Mostly my Androids are start and forget. I use Bam to change what they are running and WUProp to check that they are up and crunching. If they go down I either reboot or if being complete pigs I simply plug into them with HDMI to my monitor and wireless RI keyboard.
