anyone else lose function of the "defaults write com.apple.ScreenSharing ShowBonjourBrowser_Debug 1" screen sharing hack?
Just not the same way as before. Now when I go to my "Shared" computers section in the left-panel of Finder I can select any computer Bonjour detects and then choose "Share Screen..." I don't remember seeing that one before Snow Leopard.
i dunno if this will help, but i believe the culprit is the mDNSResponder:

defaults write com.apple.ScreenSharing \
'NSToolbar Configuration ControlToolbar' -dict-add 'TB Item Identifiers' \
'(Scale,Control,Share,Curtain,Capture,FullScreen,GetClipboard,SendClipboard,Quality)'
