923 Mbps across the Ocean ...

We have been talking to the radio astronomy people.  We are aware they have such needs, however, I am unclear whether they have succeeded in transmitting single stream TCP application to application throughput of 900Mbits/s over 10,000km on a regular basis. Perhaps you could point me to whom to talk to.  I am aware of the work of Richard Hughes-Jones of Manchester University and others and the Radio Astronomy VLBI Data Transmission (see for example http://www.hep.man.ac.uk/~rich/VLBI_web/) since we have shared notes and talked together a lot on the high performance issues.  My understanding is that for today they use special high performance tapes to ship the data around, and are actively looking at using the network.

Talk to folks that deal with radio telescopes.
