Along the lines of Markus' call for topics in the coming year...
Several people have expressed interest in more information on functional programming.
Would anyone be interested in collaborating on a session? I'd be willing to represent for Scheme, F#, and the current crop of Java 7 closure poposals. Some other ideas being Scala, Functional Java (http://functionaljava.org/), or Functional Javascript (http://osteele.com/sources/javascript/functional/).
