Yeah, it was really more of a general thing, because I didn't want to have to create custom macro methods for trivial/arbitrary stuff. For instance, I'm passing the UserName as a query string to a page, and in a Static Text web part I'd like to output the FullName of that user (not CurrentUser). There's a GetUserFullName transformation method, but I need the ID for that. I assumed there'd be a general way of querying the database to grab a value or collection of records to transform (I was also wondering why I couldn't find a Users collection the K# API in the first place).
