That artcle is a bit out of date, download my image and check out the
current version of those methods.  They work a bit differently now but I
still use them heavily and they work great.  I don't use the decay hack
anymore, I just send down some script and stop the polling.  I'm in a hotel
in New Hampshire at the moment so I don't have time to dig into any code,
but I can tell you what's in my image works well.
