Remote login with graphic "ssh"/rdp
Yes (probably). macOS supports two simultaneous user graphical sessions. One the local session and a second remote. You get unlimited ssh / xwindows environments. 

I would start with two users and your vnc of choice for remote access. The only problem is if your vnc doesn’t work like Apple screen sharing and offer the second user a choice if asking to share the session or create their own. 


Are the changes to Lion&#39;s screen sharing documented anywhere publicly?
Is there a Windows remote desktop client compatible with Lion&#39;s virtual display feature?
