Before I go too far down the route I’ve chosen, do any of my more techie and/or more experiences readers know of a blog management software (CMS) that can handle multiple subdomains and multiple users (with different priviledges) without needing more than one MySQL database?

I’ve come up with a pretty good use for one of my own domains, and will at some point migrate this blog there as well as do more tih other bits of it, but the hosting package I have only supports one MySQL without payment, my reading of Wordpress is it would need a new install and MySQL for each subdomain.

I’d love to be told I’m wrong though.
