Well, I think the emergence of UDDI/WSDL gave them a boost to speed
up, and all the core specs seem to have gained at least 1.0 status now.
I don't know if anyone has the full platform implemented yet (I think it's
unlikely), but there are parts of it being implemented - prototype ebXML
registries set up, and so forth. Sun has released an ebXML registry for
J2EE (iPlanet) that is available here:
http://www.sun.com/software/xml/developers/regrep/
but I haven't ever tried it.
They're also taking ebXML into consideration when designing the Java XML
Registry and Java XML Messaging API's which should allow you to interface
with ebXML by using a correct service implementation, approach similar to
JNDI I think.

There are open source UDDI implementations in the works, for example
jUDDI.org and pUDDIng (http://www.opensorcerer.org/).

Conversion tools from existing interfaces (ejb?) to the WSDL XML schema,
I suppose. I've always pictured WSDL as an XML IDL (but not 'human
readable' IDL, anyone who says WSDL is more readable than IDL is nuts ;-).
I guess WSDL supports a more webby definition of an interface. And its
XML, which is verry verry important :p
