I hope Dale answers this thread, but I do recall that LSL -> Plugin
communication was important to him in order to enable his TrustNet

I believe his logic was that he needed the TrustNet server requests to
come from SL in order to ensure that they were properly being
authenticated (owner key is sent in requests headers), otherwise he'd
have to set up a seperate authentication process.

Question for the Lindens:   is communication from the servers to the
client unreliable because of the udp transport?

Would you have to set up a seperate TCP channel (which I can imagine
would be quite a lot of work) in order to ensure reliable
communication between sims and client?

Even then I guess communication would have reliability issues as
compared to the current IPC via LSL llSay / lllisten..
