This would require collaboration from the workshop chair.
Nice idea - why is this in Onward?
If the OOPSLA workshops want to do this then, well, that's fine.
It may be more fun than posters: you would do it on the session just before the IceCream social (against the OnwardKeynote :-)Somtimes the Onward! keynote is the first plenary - like when Lesssig did it. -rpg
I think that some if not all of the workshop organizers would take part. Especially if we tell them up front to plan for this. It would give more exposure to their workshop, if anything, so there is some motivation there... It fits with Onward (item?!) because the ideas presented in workshops are (supposed to be?) at the outer edges of the state of the art. eb.
