Thanks for the update. The release management team is working on 
finalising the specification document. During the Sevilla meeting, 
several sessions will be around the release 3.0 topics.

OK, great.

This point is currently unknown to be included in pS3.0 at this stage.

I would rather let the release management team to answer this specific 
point.

This is currently being worked on by Frederic and Michalis. Two session 
will be organised in Sevilla on those two topics. I advise you to follow 
them.

I cannot talk about specific cases, but those should be updates to the 
existing documents (to relate the novelties).

This is a feature that is required for the LHC solution. There is a need 
to have a data push from the MP (located within the LHC site) to the SQL 
MA (located in the LHC DMz site) as the access to the local site might 
not be open for everything.

I will let Loukik provide more details and a specification about this 
specific feature.

We are expecting to have the distributed LS (renamed from mLS into dLS) 
available end of this year. The communication from the web-services to 
the LS won't change. However, if an application wishes to make use of 
the dLS, it needs to be updated.

Code delivery: November 2007
Functional test: December 2007
Release: January 2008

More specific dates will be communicated once the specification document 
and the test release plan will have been done.

Cheers,
Nicolas
