Video rental in HD and SD on PSN have been available since mid 2008. Seo Sony already has that covered. Whats new here is that HD movies may now be bought. SD was available day 1. These movies can be shared with a PSP so it could happen that they will also be transferable to a PS4 if that ever comes out.
I can easily get around 30 mbit from PSN. More than enough for streaming a movie both HD and SD. Depends on where you are I guess. I am in Norway.
What kind of wire would this router need? Is a single fibre cable enough for this kind of bandwidth? What is the limit of a fibre cable?
The first video you link to is Flash. The other one is HTML5. If the first video play and the other does not I think it is pretty clear that the reason should be pretty clear.
You could use PhyreEngine and a debug PS3. I think they cost about twice that of a normal PS3.
The reason cheating is a problem is because we are forced to play on the vendor's network,
There are quite a few Playstation 3 games that support LAN-play. You can also run the PS3 as a dedicated server in many games. Warhawk and Unreal 3 support both options. There are more games like this. Sony is not responsible for what publishers do regarding dedicated and LAN support. The PS3 allow it. I do not know about Xbox but I think you can do LAN there as well.
I am sure there are more. Sony actually encourage user generated content believing it to be the next big thing in gaming. They call it Game 2.0 or something silly like that.
