The only problem should be that people can use your small
piece of PD code for whatever they want, without even the
need to mention that it is from you. Basically you would
donate that piece of code to the world.

To run DOS on EFI-only systems, first load an implementation
of BIOS for EFI. Those are third party projects and not only
useful for DOS but also for other pre-EFI OS.

The other are unrelated topics: There are experimental 64 bit
DOS extenders and ports of thread libraries. I think almost
no DOS software uses them yet. Which specific program would
you like to run in DOS with several threads and/or CPU cores
and several GB of RAM, for example?

DOS task switching is typically done by extra software, such
as Windows 3 (allows several  VM86 based DOS windows with a
virtual graphics card etc open simultaneously) or TriDOS (it
runs only very basic DOS software) or DOSSHELL (between). If
it would not be much easier to run several DOSEMU windows on
Linux (or use Windows) people would be more motivated to go
for a free open source DOSSHELL clone.

Try smartudm and smartdft ;-)
