For anyone who wants to keep playing with it and is too lazy to type the
long commands to switch environments, I've attached the 'View' shell
script I'm currently using. This way you don't need to type the
VNC passwords.

Examples:

# launch VNC server and display on right-hand monitor
	View server 1024x768 :3
	View extend :3 east	# or: View r :3

# launch a new VNC server w/ different resolution
# display on left monitor this time due to rearranged furniture
	View server 1280x1024 :4
	View tune prev		# switch monitor to new resolution
	View extend :4 west	# or: View l :4

# show the 1024x768 VNC desktop's contents on builtin monitor
	View c :3
