Yeah your calculation look right based on there calculations; For example, with 5 users in a room with 5 webcams streaming, the bandwidth calculation is as follows:
in: 5*40 = 200 Kbytes/sec incoming bandwidth needed to the server (e.g. 1.6 Mbit) out: 5*(5-1)*40 = 800 Kbytes/sec incoming bandwidth needed from the server (e.g. 6.4 Mbit) Total traffic used after one our: 60 mins*60 secs*(200 + 800) = 3.6 Gbyte traffic per hour http://code.google.com/p/bigbluebutton/wiki/FAQ#Bandwidth_Requirements 45,000 per hour does seem a little steep to me.
