BigTurns is a hosted service and is not available as a download, so you can't install it on other servers. Trust us - this is a good thing. Managing, configuring and maintaining servers is a hard work. Servers can be picky and have mood swings. Just ask our engineers - you don't want to carry around a machine that goes "BEEEP* at 3am in the morning, just because one of the servers feels like a fresh shrimp omelet.
