In the VSE world I know for a fact that one of the TCP/IP stack vendors
offers a way to access VTAM applications without VTAM. That stack
feature just went GA before the WAVV conference this year. So, any VTAM
application could be accessed directly without having VTAM present on
the system. The applications think they're talking to VTAM, but they're
really talking to the IP stack.

The same applies to z/OS, but even worse in that TSO is required to
really do anything at least as far as "system maintenance" is required.
I don't know about VSE, but in z/OS, even with TCP/IP, it is VTAM which
is doing the actual I/O to the IP devices (well, at least with OSA
devices). Who designed this? As an "amusement", I've been trying to see
how much work I can do using z/OS's UNIX shell instead of TSO. The
answer is: "Not really very much."
As far as CICS is concerned, I can almost envision a TN3270 server
"built in" to CICS. Or perhaps a BMS/IP where BMS supports IP terminals
"directly" somehow. Of course, this will not be implemented by IBM
without a business case.
Is ICCF available via IP? Or is it even necessary? I'm not very VSE
literate.
