Licensingwise where is the difference between x86 software emulation, x86 hardware assisted emulation and new x86 processor? What I get from this is that they will do user mode emulation like qemu-user. Either way they will emulate it in software. If they would add a co-processor that would assist the emulation, would it need a license from Intel? I understand if it would run as a normal x86 core it would require it.
