I don’t remember hearing about IP for VAX/VMS 2.4, but I was part of a group at Intel in 1981 looking at ARPAnet for moving designer tools and design files as an alternate to leased bandwidth from $TELCOs using DECnet and BiSync HASP. The costs of switching from 56 Kbps to ARPAnet’s 50 Kbps convinced us to wait. Clearly, private demand drove the subsequent transition as the TCP/IP stack became effectively free.
