My home in London, UK has Plex, and when I'm in the US on business I stream movies to my mobile.
This all costs me nothing more than my standard broadband contract (GBP 30 per month for 150Mbps connection) and my mobile contract (GBP 15 per month for unlimited 4g in lots of countries).
I do rip my DVDs, but I also stream them so I don't have to choose in advance, transfer files, etc.
I have heard that they are phasing these contracts out though, and the new contracts aren't as good. I shall be holding on to this one for as long as possible.
EDIT - Unless you meant consuming from mobile, in which case I pretty much agree.
What's their policy on P2P traffic? I host fairly large data sets for analysis at work and the most stable way to get them from one place to another is via packing them into torrents. Would this be frowned on / throttled?
I didn't quite understand that. Is this only for mobile? And does it suddenly stop working if you use a Wifi hotspot rather than a capped downlink?
