Hi Peter 

Your email address of me was correct but I have been in intermittent email 
contact only, and had no time to reply yet.
I only saw Ugo on Friday, when I was only shortly able to talk with him.
The conclusions of the TIG session will be posted on the wiki site and email 
list next week.
The main cocnlusions regarding services is that download and custom are to 
have first emphasis, as we want to have demonstratable services up asap and 
not have to wait for definition and implementation of standard services.
The point about usability of level 3 services is very valid i think and we 
may want to stimulate implementors to have such services ready as well. 

Thanks 

Gerard 

PS
One other conclusion from the session was that we should start promoting the 
use of the theory mailing list for our discussions.
