We do have some people in the W3C XML Binary Characterization WG who
have gigabytes / terabytes of data. Some of them were represented at
the public Workshop we held last year -- e.g. geoglogical surveys.
You might like to look at the Use Cases document [1] for some of the
needs that have come up, and also the first go at a list of properties
of binary encodings that one might measure.

A b-tree isn't really an interchange format. W3C isn't in the business
of specifying what goes on inside a database or application in that way
really, only at the interoperability level (although DOM stretches that
a little, I admit!).
