There were eventually tweaks to the _email_ system to enable it to interoperate with other email systems (others will remember those far better than I), but that has nothing to do with the network/transport layers. The vast bulk of the early Internet work was focused on just the people using TCP/IP - and to run any of that, you needed "IP to the edge". (I am remembering of the pain we suffered at LCS before we got an IMP port so we could bring up our first IP gateway to the rest of the world...) And as for ability to run DECNET and IP on one's campus at the same time as IP - that was not the original direction taken at many places. Certainly at MIT we spent (wasted, to be honest) a lot of time trying to create an underlying data-carriage layer to carry both IP and CHAOS (and other stuff) before we went with the 'ships in the night' approach, and the multi-protocol router. But this is getting a bit off track. If you want to continue, let's move this to 'internet-history@xxxxxxxxxx'.
