Suppose your web browsing, distracted in the fact you where waiting for the SL Grid to be up again. Or you want to know constantly, what the current status of SL is? How about a taskbar icon? Just the letters SL, green for when it's UP, red for DOWN. No more constantly refreshing the web page to check the status, just glance down, there it is.
It could also tell you if your own connection is having problems. Maybe?
Just a thought from the impatient.
