Since there are two architecture precons at TechEd this year - our GAPP (Guidance about patterns & practices) and another about Identity Management - one of the Microsoft architecture teams I work with has put together a Sunday evening party at the San Diego Automotive Museum. Registration for the party is first-come, first-served using the following link:

That team is also doing some breakfast focus group meetings with architects at TechEd, and you can request to be a part of those on that same registration page. Hint: Put “Architect” in your title. <g>
