I'm putting the last touches on a CMS to generate custom NewsML feeds for internet portals. It's based on Movable Type 4.2 and allows for custom multimedia content and feeds for each portal. NewsML is a very versatile norm that allows for many, many things (its 200-page definition is frankly frightening! Thanks to L. Le Meur(*) from AFP for publishing his NewsML for Dummies [PDF, 128KB]).
MT is still lacking certain features to make it a full-blown CMS platform above its blog engine origins, but its design, template system and tags make it flexible, powerful and affordable (low learning curve and low cost) at the same time. That's its charm in my opinion for projects like this one.
(And it's always nice to see some content flow from a "tiny" MT to a "big" public portal, one can easily forget how complicated it used to be to syndicate content on the internet last century ;-).
(*) No, that's not the same LLM. ;-)
