I don't know about this.  Various versions of TPC have been offering "switched"
(i.e., very fast set-up) broadcast-quality video for some time now...broadcast
quality video is (equivalent to) 90-135 MB/s.  I don't know if it's ever done
digitally (I *do* know it's been done digitally with more setup time, as the
massive set-ups of fiber installed for the Democratic Convention and the '84
Summer Olympics by my own company, and probably similar setups by other
RBOCs.), but the bandwidth is certainly there...

...and if *that* kinda bandwidth's been there for so long, then 500 MB/s can't
be too unlikely these days.

But note, it's expensive:  it's been offered to networks and the like.
