This graphic appears around 13:45 into the talk. The blue dots are suggested locations for servers and yes, lots of them are in the oceans. –  whuber Aug 23 '11 at 19:35
    
I think you'll have to contact the authors (Wissner-Gross or Freer), because the work is scheduled to appear in print soon. –  whuber Aug 23 '11 at 19:37
    
@whuber, I hope they plan on water-proofing them! –  blah238 Aug 23 '11 at 19:42

@whuber emailed the author, who likely has bigger fish to fry. Interesting how few blue dots on west coast of US. –  Kirk Kuykendall Aug 23 '11 at 20:50
    
Had a good chuckle about this one. Good observations. Would be interested to know what the author has to say. –  Jakub Aug 24 '11 at 1:28
