Yes and no. They did indicate that there was some form of compression present in order to fit the 12G signal into a 10G ethernet NIC, which realistically means ~9200mbps max (you need to account for ethernet framing, etc, all within the 10,000,000,000 bits per second the interface supports). I think I heard that they plan to "open" the compression, similar to what they did with the BMD Raw spec, but... interoperability likely remains a concern.

If by "10G network" you mean "switch fabric with 10G edge ports and multiple 100G backbone links working in concert", then sure. If you mean "I use a 10G backbone", then, no, not so much. Dante AV is the closest thing we have at the moment, and they lean rather harder on the hardware compression. Even so, 12G-SDI is only compressed down to ~920mbit/sec/flow, iirc. And that's about 4x larger than the full-frame NDI specs so far. The Dante AV compression is based on full-frame JPEG2000, which is allegedly only single-generation lossy; as in, if you take a frame, encode it using their codec, take the output frame from that, and reencode it, you'll get the same frame back (no additional loss). With a Dante AV network and a limited number of cameras, you might be able to get away with using a single 10G link as a backbone for your switch fabric (alternatively, you could connect everything to a single switch), but with the SMPTE 2110 I don't think that a single-link 10G backbone will be viable for anything aside from HD-SDI over 2110.

For the copper stuff, yes, you can definitely send power. PoE++ (802.3bt) permits up to 100W of power (71W minimum) for type 4 devices, which delivers power over all 4 pairs (including the data pairs), or 60W (minimum 51) delivered over either 2 of all 4 pairs, depending on the class of device that is receiving the power. Minimum power spec depends on the overall length of cable from your switch. Shorter runs are obviously better, which brings us back to the limitations of the backbone links on your fabric.
