One could also toss wxPython, VTK, or any one of the other GUI libraries into the mix for visualizing those images, of which wxPython just acquired no-copy display of PIL images, and being able to manipulate them with numpy (of which some wxPython built in classes use numpy to speed up manipulation) would be very useful. I'm doubtful that this PEP alone would allow zero-copy sharing of images for display. Often, the libraries need the data in a different format. So they need to copy, even if they could understand the other format. However, the PEP won't allow "understanding" the format. If I know I have an array of 4-byte values: which of them is R, G, B, and A?

You give a name to the fields: 'R', 'G', 'B', and 'A'.
