A most excellent summation Zeph. Thanks for taking the time. I've been struggling with finding information about each device, its function and functionality with other devices. There's bits of info located in disparate places that would be best condensed into the Wiki pages.
I remember, when I got my first database programming job in my early twenties, how my boss had me start by documenting the existing system in all respects. What he was doing was giving me an opportunity to crawl through the entire software library, learn it in detail, and quantify it for future programmers.
Perhaps, each device could have a Wiki (and sticky forum post) "What it does and What it Connects to" page that includes a comprehensive description and a couple example system diagrams.
I'd be pleased to help with that effort as Zeph has here.
