A few questions:
What is the difference between the Mogami 2319 cable and the Mogami 2524 cable? Other than a 33 cent price difference...)
James, on those right angle Neutrik jacks you suggest, is the only plastic part the little black piece?
Does anyone know how to make... essentially a cableless cable... haha. I've seen people use them on pedal boards, basically just two jacks connected together for connecting pedals. Right now I'm using these $5, approx. 5" cables from Guitar Center, and for some of my pedals I don't need that much cable sticking out.
The 2319 is "mini" instrument cable. It is noticeably a smaller gauge (although I didn't measure the actual conductor). I use it for pedal cables because it does 180° bends nicely and for such a short cable I'm not worried about the impedance. I use the 2524 for long instrument cables. Although the page doesn't say anything about the 2319 being only for short runs, so maybe it's suitable for longer runs.

Regarding the NYS207, you should be able to see pretty clearly what's going on in the picture I provided. The actual signal carrying pieces are just like an all metal plug, just the backplate and the nut are plastic. For a pedal board I think they'd be fine. If your cables will be on stage getting stomped on and rolled over by gear crates, etc. Maybe an all metal jack is the way to go.
As for a male-to-male jack... I suppose you could make one, but I would recommend against it. I mean in the cost of building a cable it's all in the jacks. The cable itself for a pedal cable is pennies. So for essentially no extra cost you have a cable that has more options.
Additionally, I'd be weary of something like that because then two of your pedals are rigidly connected. Every time you stomp, kick or move one pedal, you're going to be heavily loading the jack connection on both of them which seems like bad news bears to me. Then again I have to run F.E.A. all day sometimes so maybe I'm hyper sensitive...
