It's broken with password and rar5 but the source code is helpful, maybe.

And UnRAR.dll / UnRAR source under rarlabs.com/rar_add.htm

And for linux:

github.com/m3t/urs

Script with RAR5/Password:

Two known issues:
1. No auto delete for the stream files
2. For rar5 and with password is only unrar possible. (incomplete video as preview/stream)

I hope for JD2 and/or stream_unrar (with rar5/pw) in the future.
