[this is not particularly germane to the discussion, but may be 
interesting to someone]

The LINX in London buys transit. The contracts LINX participants sign 
in order to connect to the exchange include requirements that routes 
corresponding to the numbers used to number the exchange fabrics (there 
are two of them) are not propagated to any other organisation. The LINX 
has its own AS, and originates a supernet which covers the exchange 
subnets.
