This may seem like a silly question, but, I spend an unbelievable amount of time checking for software updates on the various programs I own. Between VST plugins and 3rd party scripts and video plugs, not to mention codecs, drivers and firmware, it's practically an unending task. M$ takes care of their end with Windoze Update, but, no one else has a central update site.

Does anyone know if web software is available that will monitor a website for changes? I guess this means an automated method of querying all the websites on a user defined list to look for a change.
