Is there a WPMU plugin similar to Yoo Themes "Widgetkit" plugin?

I have been using Yoo Themes "Widgetkit" plugin in combination with a number of WPMU plugins on a few sites. If it exists I would like to use a WPMU plugin(s) in place of Widgetkit. It would be more convenient and would also probably prevent a few issues I have had with Widgetkit and some WPMU plugins not playing well together.

Is there such a WPMU product?
