I want to put a login / registration area that will float on top of the rotating header images. The login will be similar to http://www.owit-toronto.ca.

Please note that it is not going on top of the banner, but in front of the rotating header images.

For the site I am building in the current version of Atahualpha, I intend to use the s2Member plugin. It does create a wdiget that normally would go in a sidebar.

So I guess a better version of my question would be, how to cause that widget to display in the foreground of the rotating images.

Possible? Or would it only be possible over an area without the images rotating?

I suppose you could create a new widget area and position it over the rotating images with CSS but I don't know if that would play nice with IE.
