[Numpy-discussion] median filtering question -- masked arrays

Does anyone have a hint for applying a median filter to a masked 2D 
array in numarray?

I've been using the kludge of extracting a normal array with the 
masked data replaced by the overall median of the array and median 
filtering that (with the appropriate nd_image method). But this is a 
crude approximation and I'd like to do better -- preferably without 
coding my own median filter in C.
