Unfortunately, it has to be on SCO - for now. We are hoping to migrate to Linux systems, but that is still too far down the road. The primary program I maintain is right at 500,000 lines of code (yes, 5 zeros). It is going to take some work to get it to compile and run on Linux. We are planning a movement away from SCO for the reasons you state.
