Sounds really interesting. Just a pity you didn't post this before the event.
I'd be up for this I think.
My bad! I listed it as the 25th September which is obviously not the case. So just to confirm - [b:efa3b02354]Sunday 25th October 2009[/b:efa3b02354] - if you are interested please send me through your ideas to firstname.lastname@example.org
