Are Tag Clouds Accessible

Hi all,

We've been talking about using Tag Clouds in some of our work (here's an example: http://del.icio.us/tag/). We've been seeing a lot more tag clouds recently, and I wonder how it's possible for them to be accessible, especially in a screen reader. How could you go about differentiating such a list of links? Are header tags appropriate(I wouldn't think so)? I already know that del.icio.us conveys meaning in color, which is a no-no.

Has anyone tried to make accessible tag clouds before, or is it just not possible?
