With the TURNLite solution, CP/SP can easily offload the complex and troublesome deployment of TURN servers to the service provider, the service provider can easily integrate the data relay function of TURNLite server into their current distributed deployed CGN devices.

Actually, not all the communication scenarios of the “full” TURN can be achieved by the TURNLite.

The "full” TURN allows pretty high degree of the network hosts privacy. If a host is using TLS/DTLS protocol for the TURN communications, then the network infrustructure devices are not able to determine the hosts’s peer address. The peer information is stored (ephemerally) at the TURN server and it may not be retrieved by the outside parties if the TURN server is properly secured.

With the TURNLite, the communication between the parties is fully controlled by the host’s network infrastructure. That may be a desirable quality in some limited circumstances (like in a strict corporate environment), but I am not sure about the general case.
