Aggregate traffic management

Hopefully I can stay within the bounds of NANOG's traditions against 
marketing material if I limit myself to thanking Kyle for his comments, 
and encourage anyone attending NANOG 27 who would like more info on 
automated control of routing for load objectives to come find me at the 
meeting.
