It's an interesting and important observation when you say "No competent CIO is going to advertise to the world exactly what hardware and software versions are running on their systems."
Mainframe systems come with an integrity guarantee. If the system can be hacked, or otherwise broken into, IBM is on the line as well. This is part of the standard mainframe offering, not an extra charge or services offering etc. There is no reason why a CIO would not, assuming he knew what levels of hardware and software and having seen Guru speak, I bet he does.
Back in the late 1990's I architected an Internet banking system for NatWest Bank in the UK that hosted two IBM mainframes outside their corporate firewall, running as a parallel Sysplex. The system was designed to scale from 3k to 1.5million users without outage, and the largest number of users registered was 995,000 and while we did take down the servers one at a time, never took down planned or unplanned both.
Not only did we talk about it publically, but you could go to <a href="http://www.netcraft.com/" title="netcraft.com">http://www.netcraft.com/</a netcraft.com> and it would tell you what software was running... OS/390 V2. Netcraft shows just Linux and IBM HTTP Server for Nationwide. <a href="http://toolbar.netcraft.com/site_report?url=http://www.nationwide.com" title="netcraft.com">http://toolbar.netcraft.com/site_report?url=http:<nobr>/<wbr></nobr> /www.nationwide.com</a netcraft.com>
The NatWest system is no longer running on mainframes and was migrated to the typical run of the mill Intel server farm following NatWest being acquired.
