rustynailinabucket9 Yes, Play'a is from the same company (Swearl, LLC) that owns VRB network, Dezyred, VRPorn, VRSmash, and whatnot.
Regarding streaming, I think 2xVR once posted here in this forum that on average people actually watch like only 20% of a video. If this is true, the traffic of downloading an entire video would be equivalent to streaming it five times. But maybe more important, 'streaming only' means that you can access content only when subscribed, while with downloading it was possible to get the entire VRB catalogue within 3 months and then quit for a year or two.
