Who runs liveGate?

liveGate is a server program that runs on a machine that's already connected to the Multicast Internet (aka. "MBone"). It is used to provide 'ad hoc' multicast access, via a tunnel, to client machines that do not otherwise have MBone connectivity. For example:
  1. An ISP can use liveGate to provide multicast access to several of its customers, as a value-added service - i.e., to bring in additional revenue. (The ISP can also use liveGate's built-in statistics web server to monitor its customers' multicast usage.)
  2. A telecommuter can use liveGate (running at his central office) to provide multicast access to his home office.
  3. A network administrator can use liveGate - in combination with the separate "liveGate for Intranets" program - to tunnel selected multicast groups/ports across a firewall.

It's important to note, however, that liveGate is not a full substitute for providing real multicast connectivity to your client(s). Before running liveGate, you should first try to give your client(s) a proper multicast feed:

If neither of these conditions hold - e.g., your client is a Windows PC connected to the Internet via a (non-multicast-capable) dialup connection - then you can use liveGate instead. (Note that you do not need "root" permission to run liveGate.)

Finally, note that each liveGate client must also run a (different) 'controller' program that operates its end of the liveGate tunnel. Examples of such programs are the "liveGate for Intranets" multicast relaying controller, and the "liveCaster" 'datacaster'.
