Redirect serialization output?

[jakobleck]

Hive under the hood uses the TypeAdapters to transform the HiveModels in a Box into binary data that is written into a file AFAIK. And then read the other way round when needed.
Is there a simple way to redirect this serialization into some sort of stream, e.g. for transmitting the data over a network? Ideally without writing your own implementation of BinaryReader and BinaryWriter.
(Background of the question: I have a set of several dozen HiveModels and am looking for a way to create a backup mechanism without implementing a second serialisation method on top of the hive models...)

The easiest and only way I can think of is just copying the box files. (Which, of course, for encrypted boxes requires later reading them with the same AES key).
Any other suggestions?
