Workshop Exercise Design - Help Needed

I've just posted Identify Knowledge Work Tasks - Workshop Exercise which describes a workshop exercise that I'm considering using in several different workshops. I feel like it makes a lot of the discussion more concrete.

I'm really hoping that folks will help me out by:

a. telling me what they would say if they were in the workshop and
b. giving me thoughts on the exercise itself.

The last time I posted something like this it was a HUGE help and I significantly redesigned the exercise which probably saved me a lot of grief. See comments in Conference Session Breakout - which convinced me not to do it as a breakout activity. Actually, I probably never will do session breakouts unless there's a REALLY compelling reason... but I digress.
