Whether you use 128 bit random numbers, or David's non-random method,
indicating ownership is useful and I don't understand why you would not like
this information to be a part of a GUID.  My suggestion is that we strike
"GUID" and instead use UID, or change the definition of global, and adopt a
prefix convention.  For instance, an Object's UID could be something like the
following:

Farrukh scheme:
787778827728846655gfgshhg88

URN type scheme:
com-foobar-ebxml:787778827728846655gfgshhg88

Party ID type scheme:

7778889:787778827728846655gfgshhg88

URL type scheme:

object://787778827728846655gfgshhg88?PartyID=7778889&Context=DUNS


Given an object's ID and it's ownership, it is possible to find out information
about an object automagically, such as interface binding info without involving
ebXML.

syncronous browse requests using HTTP logically follows.
