Using street names as directories...

Say I want to create a community website where members log in for free and have the option of purchasing a blog. The community is based off of a live housing community that contains a total 6 streets. When a new blog is purchased it's given an address associated with it's street name. So I may register 22CherokkeDr.mywebsite.com.
What I'm wondering is if it would be possible to have a directory listing for each of the streets so that when you go to Blogs in BuddyPress you see each of the six (6) streets and when selected each street displays only the purchased blogs on that street.

Hopefully there's a plugin to hamdle this.

Any responses appreciated.
