Opening up attendance at HotNets.

HotNets has historically been invitation-only. The SIGCOMM community has recently encouraged HotNets to allow broader participation. This note reports on a HotNets 2015 experiment with a more open attendance policy, and on the results of a post-workshop survey of the attendees. Based on this experiment and the survey, the HotNets Steering Committee believes it is possible for the workshop to support broader attendance, while preserving an atmosphere that encourages free-flowing discussions.
