As I know, there is not everything ported yet, and one of the missing important features I plan to use is to crypt fs.

If I understand it correctly, the diff between send and receive and two way mirror is that one is synchronous and the other is not (sends the signal that the file have been succesfully written after all/one instance have been succesfully written).
