Just heard about the update release of the Windows SharePoint Services v3 SDK and also something called the Workflow Starter Kit. I don't know anything about the Workflow Starter Kit, but it sounds pretty helpful. The big question in my mind is what relevance it will have for Office Live users. I'll post more after we've had a chance on our team to check it out more thorougly, but for now wanted to let folks know.
It'd be my assumption that most of the Workflow Starter Kit should be relevant for Office Live Business Applications, so this could be a really nice boost for anyone trying to use workflow for their solutions.
