Web Services Activity proposal.

I'm trying to respond to the Web Services Activity Proposal but the link
for responses doesn't appear to work for me (prompts for the login, then
gives me a blank page).

I'm particularly interested in learning more about the following
statement in the proposal;

 Web Services goes beyond the requirements of the Web Architecture of
the World Wide Web, Volume One, allowing different identification and
interaction mechanisms. The Web Architecture may be updated in the
future to reflect Web Services identifications and interactions.

Have we received any comments from the Web Services team asking for
clarifications or updates on the architecture?  I'm not sure that
they're wrong, I'd just like to learn more about what they're thinking.
