I was wondering about bots too since I am on 56k. But I did try jumping into a server and playing and my ping was not that bad 220-260, which is still atrocious. It was playable but I tried other servers and it was up around 720. I guess it is a shot in the dark whether my latency will be reasonable or not. I am forever cursed with dial up.
its not really about speed of your network, its really the ping that matters. I had loads of servers with latencies of 4-7 and I presume you should have the same..
