[Numpy-discussion] casting in numarray

I'm using numarray for an audio-related application as
a buffer in an audio-processing pipeline. I would like
to be able to allocate the buffer in advance and later
regard it as a buffer of 8bit or 16bit samples as
appropriate, but in numarray, casting always produces
a new array, which I don't want. How difficult should
it be to make it possible to create an array using an
exsisting pre-allocated buffer to act as an interface
to that buffer? Also, if others consider it useful, is
there anyone willing to guide me through the code in
doing so?
