IIRC, a full feed of usenet (3 years ago) was approx 250GB+ per day. The
overwhelming majority of that was multi-part binaries. Cut them out and
you should have plenty of room across the transponder, which (again, 3
years ago) was capable of DS3 capacity.
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.
