Setting aside the discussion on serialization, this would probably be
a nice extension. The problem is to find a good (as in "widely used")
standard. Do you think the file formats used by R are good candidates
(meaning: used outside the R community)? Are these file format indeed
standardized, with precise specifications?
I've heard about HDF as well, but I have not investigated.
