certainly looks like over 500Gb/s of traffic across ams-ix.  that's a
big 'sort of hobby computer club'.  i wonder what all those hobbiests
are doing.

in all seriousness, the above post is ludicrous.  ams-ix runs one of
the most reliable exchange platforms on the planet due to an
incredible investment in optical switches and duplicate hardware.
it's expensive to run that way but the results have been incredible.

none of that is actually on-target for the original question about the
*value* (other than cost savings) of peering.

so far there have been some good values articulated and there may be
more (reach, latency, diversity of path, diversity of capacity,
control, flexibility, options, price negotation) and some additional
costs have been mentioned (capex for peering routing, opex for the
peering itself + cross connects + switch fees + additional time spent
troubleshooting routing events). 

are there others?
