TheIonix writes "Flat network cables aren't anything new, but I'm pretty sure ones like this are. Japanese accessory king Elecom today announced the "LD-VAPF/SV05" network cabling, coming in at 1.4mm thick." Also here's their press release if you can read Japanese.

If I remember, 7 meters of the flat cat6 at the time was much cheaper than anything I saw in the US for standard cable (which I buy in bulk, but I also bought the cable in Akihabara, known for its ridiculously low prices).
Also, check out http://www2.elecom.co.jp/cable/lan/index.asp Even without knowing Japanese, you can get a general idea of the types of cables they offer (they have tons of other networking products too).

The wavy lines in the back of the photo look like "twisted pair" in two dimensions, but it seems like that would only be effective against EMF coming from either side, whereas traditional twisted-pair is effective against EMF coming from all directions.
But maybe it's good enough-- not everyone needs 100% throughput, especially in a home environment.

PVC itself is fairly fire retardant, but it releases Hydrogen Chloride when heat is applied to it. Plenum rated cable burns, but it doesn't release HCl when it does so, and thus is required to be used in environments where air will be circulated.

Teflon is used for low-capacitance ratings, not necessarily for plenum cable.
Plenum cable is expensive, though. CAT5e is about $70/1000ft. Plenum CAT5e is $170/1000ft. And if you're wondering how to tell the difference just by looking at the jacket, well, you'll see some markings on it... plenum jacketting says "CMP" or "CL2P" or "CL3P", while non-plenum jackets say "CMR" or "CL2R" or "CL3R".

So, when you twist the wires together, you are ensuring that any noise that hits the wire, his both wires, in phase. This allows for very long runs. MANY techs work in this way. Nearly all serial techs, altough, some are implemented better than others.
I have no idea what you're talking about with the 'reflections in the pairs speeding up data flow'. AFAIK that makes no sense at all. You never want reflections in a transmission line.

No, the twisted wires aren't twisted to cut capacitance between those two wires. It's the crosstalk between parallel channels that you want to cut down on.
