Because SCO was/is a x86 Unix, most SCO binaries run with little or no modification on Linux when you have the right libraries and Unix compatibility kernel modules installed. Scott can post more about this. SCO has since been bought by Caldera. The latest version of SCO was renamed Caldera OpenUnix for higher end servers, while Caldera OpenLinux is for lower end servers and workstations. They made significant improvements to the SCO system allowing it to run Linux binaries natively. They are now marketing OpenUnix is a drop-in replacement upgrade for when you need to scale your system higher than what OpenLinux allows. A few months ago I read a review of OpenUnix running normal Linux software like StarOffice. The reviewer said that Linux compiled binaries ran noticeably faster on OpenUnix than Linux itself, although networking stuff seemed slower because the TCP/IP layer of SCO's kernel was less efficient than Linux. Kinda interesting how Caldera has their own dual Unix/Linux solution to have options for higher and lower end customers. This essentially mirrors Sun's Solaris for high end and Linux for low end market stance, and IBM's mainframe AIX for high end, and Intel based Linux for low end. Caldera however doesn't have the premium prices of proprietary hardware that Sun and IBM have, so they seem to be in severe financial trouble compared to those competitors.
