Thus sounds interesting. Googling however has failed me. Can anybody share
the original article or a link to more info?

act fast enough, they can buy in the cheaper market and sell at a profit in
the more expensive market before the differences iron themselves out.
These institutions have invested a lot in high-speed internet connections
between their offices physically near the various markets so they can
exploit these differences.  Looks like someone is going to try to speed
things up by using a SW radio link.  Note that the FCC applications were
filed with a request for confidential treatment of certain details.
