I use both WMP and Winamp, and I'm looking for a script for my status that supports both.  Like, when I'm playing Winamp, it shows that, and when I'm playing WMP, it shows that.  But it would need an option, for in the off chance, that both are going at the same time, that one overrides the other for the status.  Can this be done?

Not sure it's possible the way you want it. More than likely you would have to find a tool to disable the plugin in one of the media players in order to show the other. The plugin just updates the Media PSM and so you can't tell where it came from etc...
