Richard, you can make these soft proof profiles with any good
profiling package and standard targets. Though there may be some apps
that choke at such unexpected measured colors. Dan Culberston and
others started successfully doing this with Profiler Pro years ago. 
The advantage of using a neutral target is that it focuses on the
values most important to us, and not all the other unnecessary colors.
Since the target is so much smaller, printing and measuring for the
profile is very quick and easy.
I'm sure some of the expensive apps let you build and use custom
targets, but the EyeOne is much more affordable and handy for many
other tasks as well.
Regarding the questions in your previous post in this thread, these
profiles satisfy all the requirements you mention. This is indeed one
of the things color management is intended to do- accurately
characterize and display a system's output. It's the converting part
we're not utilizing.
