It's worth noting that BSON is not equivalent to JSON. All BSON objects are documents. JSON objects can be documents, lists, strings, numbers, null, or booleans. Eg, `null` is valid JSON, as is `"foo"`, but neither can be expressed in BSON. So if your criterion is 1:1 compatibility with JSON, BSON doesn't get you there. (BSON is awesome, though.)
