While it might be possible to map a small subset of the driver functionality to our voxware API, it's really not going to help much in the long run. I don't know what the correct answer is here for future direction either. ALSA has been the 'next big thing' for the past 5 years, but really doesn't seem to be living up to the promises. Should we try to implement it anyways and use it as the foundation for our next-generation PCM framework, or should we moderize the newpcm API ourselves and hope that ports authors will follow us when/if ALSA does gain traction?
