Buying IP Bandwidth Across a Peering Exchange

Yes, we could of course pay for some space and power with a shared hosting
provider, but buying a full rack and power for a single router seems silly.
The ideal person to buy the small amount of space and power from would be
the transport provider that is transporting us to Equinix, but in most
cases those are large providers like Level3 who aren't interested nor
willing to sell us a quarter of a cabinet. If we were to get space directly
with Equnix then we would have yet another cross connect from the transport
provider to our rack.

The whole point on getting to the exchange is to peer with providers like
Netflix and Google as this would be for an eyeball network, but after you
add up the cost of the rack, power, cross connects, exchange ports, etcs I
am not seeing the value in doing so. Espically with some of the Tier 1's
willing to sell us Gbps IP transit links for almost the cost of the
transport back to an peering location.
