Interoperability on diverse networks is critically important for a Linux distribution aimed in the direction that Zorin is going. One thing that is frequently needed and should be available by default (or with the flip of a switch) is RDP (Remote Desktop Protocol) screen sharing. VNC is just really so bad that I never use it on any systems anymore and X11 over ssh is worse.
I'm hoping that you take it to heart to integrate RDP functionality by default into Zorin since it would go a long way at helping users to have immediate access to a sorely needed functionality in Linux distros when working within a Windows or mixed network.
