[mary-dev] Could AudioPlayer be a interface?

[Paulo Levi]

You could send it base 64 encoded.
One of the nits about this is that to split the data you'd need to
translate the time to a number of bytes read (or emit  a end tag when
you emit silence (that has it's own bugs as i reported in the last
ticket i opened - punctuations are sometimes considered silence or not
emitted at all - i am hacking around it, but i don't think its 100% -
i just mark when there is a <boundary> with duration and skip spaces
and punctuations instead of just spaces while finding the next word).
