1080p60 over coax with QAM

There have been several recent threads on intra-building distribution of high quality signals, particularly the one on Best Buy and on bars/restaurants.

I'm asking this in curiosity; I don't even own a 1080 receiver and don't install systems, but do try to keep current on technology.

The higher end ZeeVee box offers 1080p60 out. It suggests that inputs can come via VGA (I understand this one) or component (signal makes sense, but BD players won't output 1080P except to HDMI as I understand it). Is there any 1080p source without DRM other than from a computer. I understand that the ZeeVee deinterlaces (and/or upconverts) to get the 1080p signal.

1080p receivers will accept 1080p sources via HDMI from what I have seen. Will all or some accept 1080p60 via QAM RF?

Ken, I was not (and am not) talking about A/V receivers, rather HDTV receivers. My question is whether a typical receiver which handles 720p and 1080i via QAM and 8VSB, and 1080p via HDMI can handle 1080p via QAM. I had a fatal flaw in my question, ASSUMING that 1080p over QAM even exists; my reference was wrong, so I'll amend my question to include "does QAM256 have the capability of carrying 1080p content?" I think I am aware that bandwidth prevents a 1080p signal over 8VSB modulation in the 6 MHz allocation, and thus by implication in traditional HDTV receivers.
