It seems it wouldn't be too big deal to extend the *.npy format to
include the mask.
Could one memmap both the data array and the mask?
This I haven't thought about too much yet, but I don't see why not. This does provide a back door into the mask which violates the abstractions, so I would want it to be an extremely narrow special case.

Netcdf (and assume hdf) have ways to support masks as well.
