Yes, giving more than one slot is an option and not one we've used in
the nova track before that I can recall.  It's usually because we're
trying to pack so many things into the schedule.  It's probably worth it
for some topics.

However, I still think things have to be strictly scheduled for the
design summit, as compared to very loose for meetups.  At the design
summit, there are several tracks going on at once that people need to
jump between, as well as keep up talks they are giving, or even customer
meetings.
