There's no consensus yet on what, precisely, we'll be working on, but I know I've a personal bias towards MiddleKit enhancements, DAVKit enhancements, and bringing UserKit out of its alpha-ness.
Feel free to contact me (TrippLilley, tripp+pycon-webware-sprint@perspex.com) directly about the sprint topics, or, better yet, post to webware-devel.
Note that, by design, sprints are "not intended for newbies". That doesn't mean newbies aren't welcome, it just means that our focus is going to be on enhancing the code, not teaching the code.
Now, with that said, I'm rusty on the code 
I expect that I'll personally spend at least some portion of my sprint time fleshing out and diagramming Webware's architecture, bringing up to date some of the earlier work by Chuck, Ian, and others.
I expect this exercise would be helpful to those who haven't yet peered deeply inside Webware's source, but would like to. So, uh, newbies are, in fact, welcome to this particular sprint
