I will send this one to the group, but further messages should just go to the people interested.

Is there some good reason that the ITS machines cannot be gatewayed through a supported machine? Even little 11's like the 24 should be able to run some sort of existing TCP/IP implementation. Rand-Unix currently talks to the ARPANET over a 9600 baud tty line via an 11/34 running the NCP. --Lauren--

No, there is not any real reason why we cannot set up some limited gateway. However, the design of really complete gateways with protocol translation like one would want is an unsolved research question.

In fact we will probably implement some limited functionality to connect our local network to the Internet, but we will not do any development which requires a major software effort. To implement a real TCP for an ITS machine would require about two years of heavy duty full time system programming, and since we are rapidly phasing out our timesharing machines we are not going to undertake such work. We are not going to do anything until we wake up one day and discover our plug being pulled out.
