"The entire focus of the industry is on
bandwidth, but the true killer is latency."
Professor M. Satyanarayanan,
keynote address to ACM Mobicom '96.

In short, an excellent call for end-to-end logic -- by explaining how layers
of networking software bite. If only a modem *knew* when a packet ended,
when the http stream ended, when the user click-through interrupted
the file-transfer drip... and if it could know how much the data was
*worth*, we could do a lot more with the stack.
Remember, opacity has its price.
