Question RK3066 Device - 2 Questions

I have 2 questions regarding some RK3066 Device, imito MX1's and MX2.

First off. I have noticed I can not get these RK3066 accessible to the new adb. I'm wondering if this is a driver issue on my computer or just a issue with these chips.

Next would be more of a general question. I want to be able to remotely control a android device behind a firewall with out any port forwards.
I would love a VNC server that is compatible with UltraVNC's Repeater, but most of my research in the play store return client type programs not server type programs.
