@angober - Remote Storage is not required for streaming ... using the NGNIX VOD module is the recommeneded way to stream VOD. Wowza would be an overkill for that task, and certainly not as optimized and smooth.
Remote Storage is only recommended when you have restrictions that mandate that your actual video files will be stored on a server that is different than the Kaltura server and is not accessible via the same NFS.
And there are restrictions for Remote Storage due to the files not being easily accessible, including on-the-fly thumbnail generation: https://knowledge.kaltura.com/node/1248#Storing%20the%20Source%20File
