Well, I'm currently juggling a 6GB dataset of a terrain map of the moon.
(Freely available from NASA.) 2GB isn't unreasonable.
(Feature request: memory mapped uncompressed on-disk lookup tables. I've
given up trying to feed Povray really huge datasets because the time
taken to load them into memory is crippling. If I can just leave them on
disk and use mmap() instead, then not only does only the part of the
data I need get loaded, but it remains loaded between runs. Loads, loads
faster. It's not even slightly hard when using Boost;
boost::memory_mapped_source works everywhere.)
