I asked this a few months ago, and got some helpful answers but it's still just not clicking to me.
All I end up with is convoluted messes with the .htaccess files getting screwed up causing 500 errors until I nuke .htaccess and let it create a new one.
For my example, lets say I have three blog sites I would like to have one login for, and be able to pick which one a particular post ends up on, be it one, two or all three.
But the core purpose of each site would be different. With each having it's own theme and offerings. So, would plugins/other offerings such as one has a podcast associated with it, the other has a gallery, etc.
Is this something that 3.0 can do with the networking enabled, be it multiple databases or a single. I don't care. I'm using Dreamhost, which is not cPanel voodoo, and mirroring sites is something I'd like to avoid because I don't want content from one URL to be available at the other, or to have the domain name change mid-stream.
Basically, I'm looking for a unified backend with regards to admin/posts, but pages/plugins/themes are specific to the domain.
