I wish WDX was more efficient. But I couldn't find a simpler way to save arbitrary amounts of arbitrary data from the r.h.s of expressions for reuse in a heterogeneous environment.

I think I tripped across a MathGroup post in the past months with an oblique reference to WDX as the format which carries much (all?) of the data for the *Data[] functions. That'd make sense to me.
