When defining a new IPTV service for an ISP, then what would it be?

Let's say you could define the IPTV service of an ISP. What's the features you'd like to have there?

Here's my list:

- Time shift (pause/rewind current stream)

- DVR (watch one stream, record another in parallel)

- Voice/Video calling directly from my TV with an attached webcam (plus recording of the call)

- Sync with cloud storage to easily view pics/videos taken from my phone on TV and vice versa

- Share recordings with friends

- Chat overlay to discuss in real-time a currently running show directly on the TV

- The possibility to consume a (different) stream on an iPad in parallel

- Video-on-Demand with Netflix etc.

What's your take on that?
