Hi Gang,
Mitch Tulloch, one of my favorite geeks, just did an independent review of the recently released GFI WebMonitor. Take a look at his impressions of the new release HERE. He also does a nice walk through of the installation in the article, including a gotcha with Win7 and Vista clients to watch out for.
You can get a 30 day demo of GFI WebMonitor try out yourself HERE and currently there is a on new licenses.
