Around 1994, MIT purchased a site license for a proprietary
spreadsheet program for SCO because we knew it would work on Linux
(and we had a lot of Linux usage on campus; we had ported a good chunk
of the Project Athena infrastruture, including the Andrew File System
to Linux).

An amusing anecdote; I worked with one of their primary software
developers so we could get a custom build of the software that would
only work if the IP address of the machine was 18.X.Y.Z, since MIT had
class A network.  This person would eventually become one of the
founders of Red Hat, and I told him that we were purchasing it
intended to run it on Linux.  He told me that this would be perfectly
fine, because he had compiled the iBCS binary on Linux.  Turns out the
development environment on Linux was far more developer friendly (at
least in his eyes) than SCO, so he was building a SCO/iBCS binary on
Linux.  Since he had done his basic automated regression testing on
Linux with iBCS emulation, and only later sent the binary to do QA on
the SCO client, he was quite confident that it work just _fine_ on our
student's Linux desktops.
