Bypass SBT from USB output of NAS?

Hello!
Setup: ReadyNAS Ultra 2 -> LMS 7.7.2 -> SB Controller -> SBT (Triode USB tweak) -> MyDAC USB - > Preamp

Is there an application that can "emulate" a streamer and send the stream out directly from the NAS USB with LMS?
It would be practical to still use the SB Controller as an interface to the music collection on the NAS...

Cheers
