No.  Firstly, I am reading this from the DJGPP group, where running a DOS
binary in NTVDM or DOSEMU is a legitimate concern, and secondly I have a large
collection of old DOS programs that use the flat-realmode technique, or even
proprietary ring-0 extenders, and the difficulty of keeping them working into
the future has clouded my viewpoint somewhat.

Most DOS programs do run in DOSemu or Windows 9x, even NT.  However a sure way
to
*stop* them working is to use Flat-Realmode or VCPI, hence my concern.
However if the target platform is an embedded system then there shouldn't really
be a problem with using that technique.
