Sub-Sub-Blogs — creating and importing content into a custom sub-type

At the end of the day, the developer I’m working with and I came up with two solutions:

  1. Create a new blog (via Network mode) for each individual blog and just import into that using, say, FeedWordPress.

  2. Create a new custom content type and do some mod_rewrite tweaks to put it in the path structure specified above. In the Program content type, a new field that defines the blog’s RSS feed (whether it be on-site or off-site) directs a single text link to the latest blog post.

We ended up doing the second option because it was closer to the spec and really much more elegant.
