Over in PyConLand, there has been talk about trying to set up a language summit the day before PyCon starts (the second day of tutorials). The idea is to give the core developers and Python VM implementers a day to sit around and talk about stuff without having to eat into the sprints (I am not leading the organizing of it, so I don't have any exact details beyond various ideas that have leaked over to the program committee mailing list).
But there is a worry that if people attended one or both of the summits it would cut into people's sprint time. And if any sprint group would be adversely affected by this, the core sprint would be hit the hardest since the attendees of the sprint are the most likely to attend either summit.
And so I have been tasked with asking people whether attending the summits would put a crimp in their attendance of the sprints. Please let me know if attending the summits (especially the VM one on Wednesday) would cause you to skip out on the sprints in any way.
