My Synology is a little underpowered for that solution, but I have a PC running PLEX pointed at the Synology NAS, sorted out my streaming issues, and has the bonus that I can share my library with family and friends, they just need a PLEX account.
Going to do something similar, tried pulling the network cable out for 10 seconds and that worked a treat, and a lot quicker than re-indexing over 15TB of content.
