Hi Geoff, 

the reason for the order is was the following: We want to restrict participation at the workshop. Hence, there is a requirement for a position paper (as an expression of interest). Then, the workshop organizers will read through the papers and invite some of the authors. We want to limit the participants to 40-50 persons to have a manageable group (to have discussions).

For the tutorial session we do not have the same restrictions. It is open for everyone who registers in time. I would therefore expect a punch of IETF folks to show up.

If we do the tutorial session on Friday then we require a punch of folks to arrive earlier and we do not allow them to show up at the workshop on Saturday. That feels a bit strange. 

We should nevertheless think about your suggestion.
