OK, somebody tell me why you can't take the output from one of those 'vocals
removers' and subtract that from the original source (presumably yielding what
was subtracted by the vocals remover)?  I'm sure that in practice there will
be some difficulty, but this sounds plausible, especially if working in the
DSP world for the whole process.
