An even better solution for the long-term would be to use PortAudio
(www.portaudio.com), which will give you Windows, ALSA, JACK, OSS, CoreAudio,
ASIO, and more. Basically it would be like your current strategy, except all
the subclasses have already been written and tested for you! :-)
The current stable release doesn't support JACK or ALSA, but the development
branch does (I can speak for these since I wrote them :-). So I wouldn't
suggest moving to PortAudio right now since JACK support is a priority for you,
but you may want to consider it for the long-term.
