I think this argument is oversimplifying the issue.  If it were simply a
matter of a CPU and an operating system, then perhaps it wouldn't be so
difficult, but it involves considerably more than this.  Consider that
not all z/series processors support all the instruction sets, so
immediately that restricts some assembler language uses.  What
subsystems should be installed? CICS? DB2?  Who supports all this stuff?
What about configuring the network (TCP/IP & VTAM)?  Does this also
"promote" the MVS knowledge?  Where does the DASD come from?  Tape
access?  How are USERIDs assigned?  Security?  If not, then what happens
when somebody clobbers YOUR data sets?  Who will handle the SMP/E?  Who
will ensure that somebody else doesn't simply corrupt the operating
system since the data sets are accessible for modification?

Of course if all the normal security processes have to be in place to
protect the integrity of the environment, then we are certainly not
dealing with a simple implementation and it certainly couldn't be made
available to just anyone with "access to a phone".

In short, the issue of supporting a bunch of unknown users is neither
trivial, nor cheap.  In fact, a strong argument could be made that every
systems programmer with a "sandbox" LPAR already has his/her system.  

Anyway ... My two cents
