I've read the additions to the document and I like the additional 
alternative discovery mechanism which uses multicast.  Perhaps other 
mechanisms in a grid fabric might also use multicast to convey information.
<AD>IN THEORY YES </AD>

What is your opinion on this possibility:  When a user submits a job 
request (via a portal for instance), the job manager would convey the 
request to other services which trigger the (potential) instantiation of 
new services.  Any new service addresses are returned as part of the 
instantian process and are conveyed directly to the information services 
and others.   Since the locations (EPRs or WS-Names) of the services are 
passed around in an event driven model, would it obviated the need for 
searching (discovery)?
<AD>WHERE IS MULTICAST USED HERE, IT CERTAINLY IS APPROPRIATE FOR SERVICES TO ANNOUNCE
THEMSELVES WHEN THEY ARE INSTANTIATED. AN INFORMATION SERVICE CAN "LISTEN" TO SUCH ANNOUCEMENTS
AND REGISTER SUCH SERVICES DYNAMICALLY. </AD>

I thought the naming section was important.  Was it replaced by 
something else or moved elsewhere?

<AD> MOVED - SEE ANDREAS MESSAGE </AD>
