Can anyone calculate how much bandwith this needs?

Quick head math says 180,000GB thus far!

really depends on how big the pipes are and how many servers there are. I built the large gamespy network a few years ago and this is how it breaks down basically. your average company looks at it like 200 KBps per customer. thats 2 Mbps basically.if they are totally full then they need huge pipe. thats 500 customers per gigabit pipe. we used to do 3 gigabit pipes for gamespy so 1500 hi speed users could download simultaneously. obviously gamespy was not the only source and all of those sevices have queing built in to their servers. thats way free customers have to wait.at 2 megs the download a little better than this calculation 200 KBps x 5 is 1 megabyte every 5 seconds x 365 is equal to 1825 seconds divided by 60 is 30 minutes per user. 30 minutes per user in a 24 hout day 400 users per hour x 24 or 9600 downloads per service. hope that helps

The game looks good ..i will give it a try

Topic but off topic; I was a huge fan of AOE and this one looks good.

I can already see my production levels dropping....
