I'd heard that WP and MU were fully merging in WP 3.0. Did this happen? Is it now just a matter of installing the latest version of WP and turning on a multiple blog support switch...or is it more complicated than that?

Any insight anyone can provide would be most appreciated.

While it is a little easier to get running, the basic functionality is still the same. You need to ask your host if they support wildcard subdomains (if you want subdomains) and pretty permalinks is a requirement because it relies heavily on htaccess.
