Note that there are really two kinds of menus... DHTML popup menus that 
should support CSS styles and be similar to DHTML menus on the Web 
today (I believe these should be specifiable just on <ul>/<li> entirely 
using CSS, e.g., with new display types).

For native menus, I don't think a menubar widget makes any real sense 
unless you are a top-level window.  I'm not sure that's within the 
scope of Web Forms, but perhaps it is in the scope of Web Apps.
