I would also love to see a z/OS hobbyist program. Sadly, I doubt IBM is ever going to do it (but you never know).
In the meantime, anyone can download and run the public domain MVS 3.8J, it is ancient but it includes a lot of the basic technologies of z/OS (JCL, JES2, VSAM, VTAM, TSO, 3270, etc), just in much older versions (essentially 1970s vintage).
I believe TK4- includes the MVT COBOL compiler from 1972 (which was the last COBOL compiler version IBM released into the public domain), although I've never tried it myself.

I think TK4- is the easiest way to run it: http://wotho.ethz.ch/tk4-/
