This was a problem that interested me a few years ago so I made a
solution that worked with any archive and I presented it at BoostCon
(now CppNow). It was inefficient, hacky and required no modifications to
existing archives but forward compatibility did work so I know it is
completely possible. The proposal itself doesn't seem impossible, at a
