Maybe. By including VGA, the signal will be converted from a digital signal to analog, then back to digital. This might affect visual quality and color reproduction, and limit max resolution to about 1080p.

Yes, make it digital and public so it can be easily hacked, infiltrated, seized, and deleted.

Brilliant.
