PS3 remote play and general questions

1) Yes, you can remote play over the internet if you want...but frankly, it's awful. Both the PS3 and Vita just don't have great networking hardware (and hardware in general), and the requirements for having a good, lowest latency possible remote play experience is way beyond anything the Vita and PS3 could do (and even the Vita and PS4 remote play over internet is basically unplayable). Even remote playing in the same house with the same router can be rough because there's still lag that makes playing most games just unideal.

2) No, because the Vita doesn't support remote play over 3G. This is because 3G is laughably slow, so remote play wouldn't be remotely usable with it. Remember 3G maxes out at like 3-4mbps in real speeds.

3) Sure, so far nobody has been banned yet for modding the Vita and going online beyond a few people that were banned for trophy hacking.

4) Depends entirely on you. I prefer the OLED screen myself, since I don't really care about micro USB charging now that I have almost no micro USB devices anywhere in my house, and the extra internal storage is meaningless when you're hacked.


Something you should also keep in mind is that for PS3 Remote play the vast majority of games aren't supported officially, your PS3 has to be running CFW to remote play most PS3 games (although all PS1 BC games work, but that'd be silly considering you can just use Adrenaline for all PS1 games on the Vita itself). You asked about Dragon Crown and FFX/2, neither of those games officially support PS3 remote play. The list of PS3 games that do support it officially is like...maybe 10 games, the major ones being ICO/Shadow of the Colossus, God of War, and LBP2 with the rest being mostly shovelware stuff.

 

@Tom Bombadildo is correct. remote play with the ps3 is horrible. I've only tried it like once, but it was pretty bad. remote play on the ps4 is supposed to be quite good, but I haven't tried it there. I think you need an activated account, which you can do with account activator. I think even 7.02 is capable of it (it's the only thing account activator is good for on that firmware). I don't know what the ps4 file is called, but the vita file for remote play is called myprofile.dat (located here):



there's even a generator to create a fake one, because you have to have signed into psn on the vita as well.

 

The ideal speeds for Remote play, according to Sony, is 15mbps upload and download, so if your family home is sitting at only 6-7mbps (assuming your upload speed is the same), that really wouldn't be fast enough anyways even if your PS3 was hacked so it's kind of a lost cause regardless. You'd probably be better off spending the money on having your PS3 shipped to your new home as opposed to buying a Vita if your main focus was PS3 remote play, would be the best experience
