We have reserved one hour of the NANOG 40 agenda for "Lightning Talks". A lightning talk is a very short presentation or speech by any attendee on any topic relevant to the NANOG audience. These are limited to ten minutes; this will be strictly enforced. If you have a topic that's timely, interesting, or even a crackpot idea you want to share, we encourage you to consider presenting it. The Program Committee will decide which submissions are relevant (using criteria based on the NANOG mailing list AUP) and choose the best six to be presented. Use of slides is optional. All slides must be in PDF or Powerpoint format, and will be loaded in advance onto the speaker laptop on the podium. There is a good overview of the use of lightning talks at the Perl conference at http://www.perl.com/pub/a/2004/07/30/lightningtalk.html. Although their format is slightly different, many of their ideas will apply here. To submit a lightning talk proposal for NANOG 40, go to http://www.nanogpc.org/lightning/ See you in Bellevue!
