UDDI Web Service Discovery Idea

Anytime there is a central database there is central control - and you always have the "out of sight out of mind" problem of reminding people to MAINTAIN their info.
Web Services have been around for years now, but finding out what services are available on a site has been drawn out due to the centralized method (IBM and Microsoft both had directories up, now fallen out of favor.)
I think it would be much easier to find out what web services are on a site if there was a simple XML file called UDDI.XML at the root of a server that listed all the public services it had on it.
Advantages: Maintained by the web site owner, easily updated, and discoverable by web bots who could then index and be used to FIND these services.
Just another subset of info to filter on by a Search Engine.
Added bonus It is Federated - no one entity controls it - and self documenting - it is on that site so trying to figure out the the domain is self evident. (you would still put that info in the XML file.)
Now has anyone ever thought of this before?
