[request] Recent Featured Blog Posts Feed

Is there any way to hack the Recent Global Posts Feed plugin so it only pulls posts from specified blogs, instead of all blogs? If not, please consider this a request for a plugin that will create an RSS feed for posts from specific blogs.

We have a number of "Featured Blogs" and would like to have a feed that pulls posts from only those blogs. We would then use that feed in the new Multisite Dashboard Feed Widget so all members would see the latest posts from these blogs in their dashboard. Neat, huh?

Extra Credit: Creating a new Recent Featured Blog Posts Widget (similar to Recent Global Posts Widget) would be just dandy too!

I'm hoping it might be easy enough to add a config section to the Global Posts Feed plugin where desired site IDs could be listed. Thanks for the consideration!
