Just wanted to say I have been working with this and it works great! I was using m466 and Mavericks 10.9.5
Thumbnail exchange was solid even for a full HD of 480 GB of clips.
MSEX quality was better than I have seen in other applications and looked really nice in MA3D. I would highly recommend this to anyone who wants this functionality. Also seemed really low on resource use, like 0.5% CPU.
Nice tutorials for setup too.

Thanks Thomas,
