Using SCO's Linux Kernel Personality software, they can run Linux software on UnixWare. This might also be used in AIX 5L, according to Ransom Love." The Caldera folks have been talking about this for a long time; what remains to be seen is whether enough customers are interested in the hybrid commercial / Free software system to pay the premium for it. The article quotes Ransom Love as downplaying the touted features of 2.4, saying, "It will probably take another three years to build a [truly enterprise-ready] Linux kernel."
