Seems like a great idea, but... Didn't work on Chrome 2.0.168.0 (shows "An error occured...", downloads .exe, silently does something, "Installed!", restarting Chrome, same routine: error, exe...). Didn't work on Firefox 3.0.10 (shows "An error occured...", downloads plug-in, restarts FF, then same again: error, plugin). Didn't work on Opera 10.00 alpha (doesn't even show list of browsers).
