For any case where DBCollection takes a DBObject i would like to be able to pass raw/binary BSON, rather than build a concrete DBObject object such as BasicDBObject.

For my usecase i need to serialize DBObjects offline before i eventually update/insert them into DBCollection.

So rather than serialize offline, then deserialize, then build a DBObject, then call DBCollection, which then serializes the DBObject to BSON for transport over-the-wire to the Mongodb, i would rather serialize offline directly to binary BSON, then pass the BSON directly to DBCollection.

It appears that RawDBObject is exactly what i need, but there is no public constructor and no usage doc or any tests that i can see?
