As has been mentioned before, the timing of this meeting is particularly bad
for those who have to travel long distances to both coasts, since IETF is the
week immediately prior to this one. Personally, this isn't a problem, since
San Diego is a very short trip from the Bay Area, but I suspect that others
may have more difficulty.
The $600 registration fee for this event also begs the question of what, if
any, value the ISOC brings to NANOG.
