I have to manage several Macs in a lot of locations and I was very confortable with the Bonjour discovery, saved connections, and hidden features of the 10.5 Screen Sharing app. Alas, with the release of 10.6, they have gone -- Apple wants to sell Apple Remote Desktop.
I have found that using this command in Terminal...
defaults write com.apple.ScreenSharing controlObserveQuality n
...changes the quality of the connection's display, based on the value of n:
- 1 = black and white
- 2 = grayscale
- 3 = 8-bit color
- 4 = 16-bit color
- 5 = full color
I also set up shortcuts using the vnc://192.168.0.1 URL convention in Safari, as discussed in this hint and comments. I save all my connection shortcuts in a folder, and put that folder in my Dock. I now have a Saved Connections folder that I can use to launch Screen Sharing automatically.
[robg adds: This Terminal command was covered in this comment, but I felt it worth repeating as a full hint. If you have a Screen Sharing session currently open, you'll need to close and reopen it to see the changes.]
