Surely there is an upper bound on thhe useful speed of graphics. Data
transfer rate of usual color workstation is about 200Mbytes/sec. So,
1Gbytes/sec network is perhaps enough for near-realtime image transfer.

Perhaps, "high speed network" is not fast enough for realtime image transfer.

As for file transfer, there is no theoretical upper bound because of
buffer caching and disk striping.
