well, correct me if i'm wrong but, couldn't we use libsamplerate on the
fly to convert where needed at all output stages?
we could have options to select the converter, optional obstructive 
warning dialogs (for the paranoid and forgetful) and some sort of
visual indicator that highlights when source and output rates
don't match?

it's not just useful for jack either, the alsa plug layer resampler is
limited by (current) design to linear interpolation iirc, so application
side resampling (albeit via libsamplerate) would be a improvement there
too.

i was also wondering if we could use libsamplerate to handle scrubbing?
