I installed the U of Wisconsin DARPA project TCP/IP VM/CMS stack around 1986-ish, and (as I remember) it was indeed ported to MVS. IBM also rolled out their own VM/CMS stack version, and we had quite a jolly time converting. UW code had enhancements that IBM didn't have yet, and vice versa. The network connection was through a DACU (which featured an IBM PC running it) to a Network Systems Corp Hyperchannel Wisely, IBM rewrote the original Pascal code, but it was fun and educational going though the source while we had it.
