As I said before, it is doable, but I don't know if I will have time
enough to implement this myself.

Well, one of the ideas that I'm toying long time ago is to provide the
capability to Numexpr to work with PyTables disk-based objects. That
way, you would be able to evaluate potentially complex expressions by
using data that is completely on-disk. But this might be a completely
different thing of what you are talking about.
