How big a file is acceptable to distribute via GHNS? 75MB, 750MB,
7.5GB? None of these?
How big a file is acceptable to host on kde.org for download?
People seem interested in a streaming solution a la OpenStreetMaps,
but for now I want to think about distributing the entire catalog,
because I think it would be annoying to have to wait for the stars to
appear every time I reposition the display, and I do not want to
require a live network connection.
It's possible that we'll eventually do a hybrid solution (e.g., the
brightest 1 million stars are stored locally for immediate access, and
anything fainter is streamed over the net). But for now I just need
to know at what point a file is too large for our standard
distribution methods (GHNS and ftp.kde.org).
