The only place I can find anything about this is on the QNAP forums (Cant access twonky from LAN - QNAP NAS Community Forum) where it's included in a command-line setup script. Looks like it's some kind of NAS related service or thing.

It's related to the Twonky Media server.
It's a media server, I think the DLNA server.
NMC Queue Handler showed up on my network when I installed a Seagate Personal Cloud NAS.
