If you add ?format=json to a request for an OPML file, you'll get a JSON representation of the outline. This is useful for single-page JavaScript apps that want to use the outlineBrowser toolkit to diplay the contents. An example of this is davewiner.com.
-I also figured out how to write a JS page that's served by PagePark that returns the JSON representation of any OPML file. Here's a gist containing the code. And a call to that page. It's extra-nice that this feature could be added without modifying PagePark. It's starting to become a real platform! :-)

In both cases, the CORS header allows access from anywhere.
