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.
