Myself I'm a bit worried about whether we should improve our DOS support even further. The problem is that more and more people are moving over to 64-bit Linux. While you can run 32-bit programs on a 64-bit system, there is no protected mode support (vm86; there is emulation in some cases using a kernel module).
There's protected mode 32 bit, protected mode 16 bit, but no vm86 16 bit. So no real mode apps in Wine. We'd need to integrate a CPU emulator or JIT compiler into Wine to get this working.
DOSBox does something like this already. I lack ideas about to what extent DOSBox could be integrated, but at least its CPU emulator could do. Or maybe DOSBox could even be bridged/integrated and do all the DOS stuff here?
Then IIRC there were discussions in the past about integrating Qemu into Wine. Some folks at Darwine have achieved this to some degree: [1]
That probably won't fly directly [2] but some aspects of the design of an emulator integration can be investigated already, IMHO.
