The PharLap "DOS Extender" is what you cannot distribute unless you pay royalties. That thing is a 250+k clunk of code that gets "bound" to the application. IPAS do not get bound to the extender as they run as child processes of 3D Studio which _is_ bound to the DOS Extender. Think of PharLap as a Protected Mode -> Real Mode -> Protected Mode bridge. It's not much more than that. The bulk of the code is in supporting almost all kinds of system calls (you are now making int 21h's in protected mode and DOS down below doesn't even know what that means).
