You can control an unlimited number of websites and authors on one install of MovableType. Does WP let you work with more than one site yet?

The system works with your own templates, so if you have a validating XHTML template MT can work in the background to fill in information where you tell it. It makes a nice CMS and the interface has been used by non-technical people for years.

You seem pretty set on WP, which is fine if it meets your needs, but I thought I'd mention another capable platform.
