News on the back burner after PDC via the Microsoft Startup Labs developer blog - 4 apps to get you going with Live Mesh.  They are:

• Collaborative Crossword: A crossword puzzle designed for multiple users to solve together
• CorkBoard: "Bulletin board for the digital life"
• MeshLists: A list creation/sharing tool
• CrowdVote: A collaborative group-polling tool

You need a PDC Live Mesh token to get access of course. 

What would you like to see added to the MeshPack?
