I would be interested if i would be able to stream all of my own content to all of my iDevices from my own server at home, streaming everything from Apple's cloud will have monthly cost i'm sure and paying more then enough monthly as it is.
You can do that on the new Apple TV. Heck, you could do that on the old Apple TV. Or did you think only content bought from iTunes could be played on an Apple TV?
That's a mistake a lot of people seem to make and don't understand. Yes, your ripped DVDs and Blu Rays play on the Apple TV as well as HD video you record on your own cameras. Plus of course music and photos as well.
The only limitation is that it must fall within the specs of the device. For video that is mainly h.264 up to 720p/30fps in .mp4, .m4v, or .mov formats but there are others.
For the full list see the specs here:

If your video isn't in a supported format (.mkv, .avi, 1080p, etc.) you can convert it or possibly just Airplay it to your Apple TV from your iPhone, iPod Touch, or iPad using an app like Air Video which converts the video on the fly.
