LANWAR via their Facebook page mentions they have 1Gbps symmetric pipe (so 1Gbps Up and 1Gbps Down). That way you can stream as much as you want. They warn however, that even a 1Gbps pipe can get saturated (especially early in the event) when everyone is downloading new games on steam so please help avoid that by updating your games before the event.
