connector
Where can I find a female RJ45 connector that can be crimped to another cable rather than being soldered to a PCB or installed in a wall or plastic enclosure?

While we're at it, I'd love to find female RJ11 and RJ12 connectors with the same property.

Q. How will HDMI change the way we interface with our entertainment systems? The most tangible and immediate way that HDMI changes the way we interface with our components is in the set-up. One cable replaces up to 11 analog cables, highly simplifying the setting up of a home theater as well as supporting the aesthetics of new component design with cable simplification.
Next, when the consumer turns on the HDMI-connected system, the video is of higher quality since the signal has been neither compressed nor converted from digital to analog and back.
Lastly, because of the two-way communication capabilities of HDMI, components that are connected via HDMI constantly talk to each other in the background, exchanging key profile information so that content is sent in the best format without the user having to scroll through set-up menus. The HDMI specification also includes the option for manufacturers to include CEC functionality (Consumer Electronics Control), a set of commands that utilizes HDMI’s two- way communication to allow for single remote control of any CEC-enabled devices connected with HDMI. For example, CEC includes one-touch play, so that one touch of play on the DVD will trigger the necessary commands over HDMI for the entire system to power on and auto-configure itself to respond to the command. CEC has a variety of common commands as part of its command set, and manufacturers who implement CEC must do so in a way that ensures that these common command sets interoperate amongst all devices, regardless of manufacturer.
It's pretty clear that in the standard, they were trying to make sure that you would ALWAYS have the right cable when trying to assemble consumer-grade AV systems, and one way to do that is to have one cable style. Also, they want to play up the two-way communication features of HDMI.
Of course, that's speculation, but I can honestly assert that I've never cursed at HDMI connections anywhere near as loudly as I've cursed at USB connections.
If "daisy-chaining" means that data will come in on "I2C0" and be repeated out "I2C1", you shouldn't have many problems other than your slaves being too busy responding to interrupts to measure anything.
"Daisy-chaining" could also mean bussing them.
In either case, consider raising your voltage and/or using a buffer/line-driver (at least between the longest runs). This approaches a redesign of RS-232.
Simple and might be good enough:

@msutherl I wouldn't exactly call what you found in the local electronics store a crimp connector. Technically that would be a punch down connection. This wouldn't have the same strain resistance that true crimped on connector would have.
