I was thinking a bit more about the hackerspace python workshop...
could there be an easier way to have 10 people share a session than typing all their names/emails, having them all create accounts or check their email, etc.? If you have to close the shell and restart another one, same thing again...
maybe one could just have some hard-to-guess URL for the shell and everybody visiting that URL is on the same shell?
or maybe even for a whole workspace (all shells)?
