Is there any application that can be installed in OS X (Lion) that will allow a person to run applications from the host system on a guest system, displaying only the windows for the application? In other words, can Cocoa applications display their windows on another OS X Desktop than the machine on which they are running?
X11 allows you to run an application remotely without sharing the whole Desktop.
I am currently using VNC (Screen Sharing), but because of screen resolution differences, it isn't ideal.
