Stream segments of a FITS file over network protocols #3446
This is mostly directed at @embray, I think.
The CFITSIO docs indicate that FITS files can be opened read-only over a network protocol.
I want to do a total overhaul though of how pyfits handles I/O, and in particular I want to make it possible to read in, for example, just a single HDU without having to scan for every HDU in a file. For your example of large data cubes over the network this would be especially important, as we would want to read only ranges of the file. That level of support is definitely not possible at the moment (though possibly within the scope of the I/O rework).
