Nothing wrong with wanting to use a Rb as the clock source for the board. I
*almost* decided to go that route since I had a spare
LPRO sitting around. But I realized that I would never need that long of
hold-over so it would kind of be a waste. I've been looking
at some cheap ($20 USD) 1PPM TCXO

Actually I was planning on getting a 33.8688 MHz TCXO, apparently there's a few
sellers with them because they are used for
audiophiles in their CD players? That way I don't have to use a clock-block or
other circuitry to get a usable frequency.

It's a crazy world when it comes to self signed certs.
You have at least 5 OS's you need to consider (MS, Linux/FBSD, OS-X, I-OS,
Android). You need to think about both browsers and mail clients. Each of those
come from a half dozen sources on each platform. Then you have configuration
