Use GigE cards on the servers with a jumbo MTU and only buy IP network
access from a service provider who supports jumbo MTUs end-to-end
through their network.

Install a pair of Linux servers and use them to send/receive the data
over the WAN.

Also, do some googling for Internet Speed Record and read pages like
this one:

And read up on scaling MTI size with bandwidth here:
