There are a ton of non-standard everyone does their own thing products out there. The biggest are Netflix and the like. Look at the top of a current generation Blu-ray Disc player for a good idea of this stuff.
Frankly, you shouldn't be looking at any receivers to deliver these products because they end up being buggy, constantly needing firmware updates, and often underperform on the main reason you go it - taking care of your A/V amplification and switching needs.
Ultraviolet, for video, is one of the newest mass-adoption products coming down the pipeline. It will feature online ownership storage for your movie collection. Any device in your home, or on the road, accessing any of your movie collection at any time.
Here's what they aren't telling us: How they are going to get consumers with SOME sort of monthly or annual fee to store our stuff on their servers.
It'll happen, it's all a plan to end up hurting consumers instead of giving us a solid product which we can control. That is... Your iPhone already should be able to send your photos to your home Mac/PC and offer content sharing capabilities across the Internet as you see fit. But, of course, that really isn't the case.

Apple specifically bugs me with how outlandishly proprietary they are with their stuff. I absolutely hate my AppleTV after having it for 2-3 years nobody was using it. Have had a Dune for less than 6 months and we are fighting over who gets to use it next. Apple's proprietary systems will not be good in a world that has a ton of different formats for audio, video, and ways to take photos/videos.
