No one said you couldn't deemphasize with external software, they just
questioned how good a job it would do.  The whole point of adding
emphasis was to move the low level, high frequency parts of the audio
spectrum up in level, to reduce the quantization noise.  Filtering was
intended to be done in the analog domain, and the best DAC's implement
it this way.  

Doing it digitally is certainly possible, but it defeats the purpose. 
If you were to do it digitally, the best way would be to convert the
file to a 24 bit fomat, apply the filter, and then apply an appropriate
dithering (and keep the data at 24 bit).  Most implementations apply the
filter to a 16 bit word, and truncate rather than dithering the result.
