On a gigantic pile of money.
Well I was illustrating a point about the process more than naming specific technologies. I don't deal with specifics.
That being said, we are talking about an industry that still primarily depends on serial communications.
I work in the gaming (Gambling) industry.
Many states require us to submit both the source code and build tools required to make an exact (and I mean 'same md5sum') copy of the binary that is running on a slot machine on the floor.. to an extent that would blow you away.
They need to be able to go to the floor of a casino, rip out the drive or card containing the software, take it back to THEIR office, and build another exact image of the same drive or SD card.
I can tell you the amount of effort that goes into this is monumental. There can be no dynamically generated symbols at compile time. The files must be built compiled and written to disk exactly the same every time. The filesystem can't have modify or creation times because those would change.
This is a silly idea for open source software, the only industry I've seen apply it is perhaps the least-open one in the world.
HP already put those into a new product: http://h17007.www1.hp.com/us/en/enterprise/servers/management/insight-control/index.aspx
NetWare 5 and up had a built-in X11 console that would let you administer many of the server components from it. In fact, if you installed Novell BorderManager or any number of other features, this was sometimes the ONLY way to install or configure them.
NetWare 4.11 and below had to be administered from the "NetWare Administrator" or whatever it was running on a workstation.
