Well, for sure I was targeting high-bandwidth network when I proposed
that. To give an answer to your statement I'll quote this paper [0]
entitled 'On the Performance of Wide-Area Thin Client Computing':
"We conducted our experiments using Internet2 because it provides the
kind of high-bandwidth network access that we expect will become
increasingly cost-effective and accessible in future WAN environments."
"Our results show that thin-client computing in a WAN environment can
deliver acceptable performance over Internet2, even when client and
server are located thousands of miles apart on opposite ends of the
country".
