I have had this plugin installed on the site I'm working on for a few months now but never actually decided (needed) to use it till today. Looks promising.
One MINOR thing though. I have widgets on pages plugin installed and in use. I have several sidebars using it. Dynamic Widgets sees all the sidebars created with widgets on pages but none of them have a title. Haven't really delved in to far or actually assigned widgets yet but that was the first problem I faced. Couldn't figure out which sidebar was what. It would get even more confusing if all the sidebars had the same widgets in them. thanks.
