I traded homework assignments for honey-doos a long time ago - thank you.
But all on my own I'll go you one better and suggest one big collaboration. That is, instead of the sponsor's dollars/loonies and manpower going to a team or three, it all goes into a general fund. Share and share alike.
Hum, sometimes when an idea gets taken to the extreme it stops looking so good.
They tried something like that in the Soviet Union - on a much bigger scale mind you, but it didn't work out.
So, we have to ask ourselves just where to draw the line on collaboration. In my opinion, we've already crossed it.
