According to contacts at some of the big outsourcing providers, bandwidth 
reqirement for a 'full feed' these days, substantially exceeds the capacity of
100mbit full-duplex ethernet. something like 1.5+TB/day.  Growth rate in still 
excess of 30% annually.  Most of the recent traffic growth coming from Denmark.
