Remote play via internet? Well, this requires your ps4 to be always online, always connected. On top of that you need a decent internet-access. Given most consumer-internet is asymmetric you better look for a good access with high upload. On top of that you better have a low latency at your access. On top of that nobody should use your internet-connection while ps4 is streaming. On top of that ps4 will have to leave low-power-mode and will consume a lot of power. On top of that if you play via 3g you won't have a good experience because of latency. On top of that it will eat up a lot of data from your limited data-plan. If you want to play via wifi at any remote location it will highly depend on how the internet-access is where you get your wifi from.
Yeah, sounds good :)
