My b2evolution Version: Not Entered

Lately I have been looking for an alternative to WordPress and of course I stumbled into b2evolution. I loved the demo and it looks awesome, but even after reading a lot posts on sub domains and how to set them up, I keep wondering if there is an easier way of doing it?

I have several different domains and one in particular I would call my "regular" one. It also hosts a few sub domains that each have a WP installation that I would love to convert to b2. Other than installing a separate install of b2 for each one is there an easier way to do a single install that can support all the sub domain without all the .htaccess voodoo and stub file stuff?

Sorry for my thickheaded question, but it just seems to me that such a powerful blogging system would have a better way than what I am assuming at this point is the only way to do it.

Thanks,
