[SciPy-User] FIR filter with arbitrary frequency response

I was wondering if anyone has already written Python code to design
FIR filters with arbitrary (given) frequency response via
IDFT+windowing, a la 'fir2' in octave/matlab?
 (Theory: http://www.dspguide.com/ch17/1.htm)

I don't see it in scipy, but it seems generally useful. (I might end
up writing it if no-one else has, but I'm not sure yet whether it's
actually useful for my problem.)
