I got a few friends with bad internet connection and they keep signing in and out like every 10 seconds.  The toast is useful, but it is also pretty annoying since that window will block that area so you can't press anything.  I usually like to put my WMP or iTune dock in that corner and sometime when I want to press the button "play, stop, etc.", I hit that toast as it pops up! 
Does anyone have a script to make that toast smaller or make it pop up somewhere else on the desktop?
