Oxite offers support for multiple blogs per site.
”Oxite includes the ability to create and edit an arbitrary set of pages on your site. Want an ‘about’ page? You got it. Need a special page about your dogs, with sub-pages for each of those special animals? Yep, no worries,” Microsoft continues. “The ability to add pages as a child of another page is all built in. The web-based editing and creation interface lets you put whatever HTML you want onto your pages, and the built-in authentication system means that only you will be able to edit them.
