Actually Nomad would exceed the Hopper in that respect. You off load the recordings onto the device (tablet, phone, laptop, etc.) and don't need an internet connection to watch the recording. In this case Nomad would satisfy both 2. & 3.
As for 4. in your list; DIRECTV Anywhere meets that criteria. And, you don’t have to have an HR44 to use it.
If someone needs the added capacity they could install a 4TB eSATA drive. And let’s face it, most people don’t need to store more than 200 hours of HD, but if they did they could have double the capacity of the Hopper. I don’t know about you but I delete recordings after I watch them so 200+ hours of HD is more than enough for me.
So, in reality you’d only need to add the Nomad and if you really needed the space, the eSATA drive.
Having seen Dish's Sling with Hopper firsthand in detail here at CES, and having asked a variety of questions of onsite engineering leads in their booth...once folks got past the marketing propaganda...the devil was indeed in the details, especially with a number of limitations for the Dish offering intended to compete with DirecTV's nomad.
The Sling with Hopper HD DVR boasts a 2TB drive, but a portion of that capacity is not actually usable for customer recordings. Both the DirecTV and Dish storage capacities can be augmented to larger sizes.
Having used nomad for some time, and now closely seen what Dish will offer about 1/17/13...it became clear that from a capability and technology standpoint, the Dish offering is roughly 1 year behind nomad in it's evolution and also contains a number of significant user limitations.
