Shane,
HMC works "OK" for NIP messages.

John,
In a Parallel Sysplex VTAM and TCPIP are always UP! So there is ALWAYS an
available SMCS console when you IPL.
IMHO bad idea. BTDT many times. Any JES2 problem (i.e. question about
checkpoints) and you're blind: you don't see whole message, but ou have
to answer them. I don't like it.
Yes, I do agree that in a single image system that SMCS is not ideal, but
isn't parallel sysplex what we all should be aiming for to ensure the future
of z/OS?
At the least you could have 2 images active in plex on a single box.
I doubt anyone establish single box sysplex just to have consoles
available. Sysplex is good thing from availability point of view, but it
consumes more resources and costs you CPU cycles. Single system on
single box will be faster.
In this case (consoles) I would buy OSA card for OSA-ICC consoles or
second-hand 2074, or 3174, or Securagent box, or Visara SCON... I
believe each of them is cheaper than sysplex. <g>
My $0.02
