I was thinking about the 5V output. I think I'll do a little rearranging and give room for a little switching module, the one I use on the Super-Chuffer. It has the same pinout as the LM7805T, just needs slightly more room on the board. Of course, if you're drawing more current, another consideration is making the filter caps more robust, that's another limiting factor.
I thought about the design overnight, and I realize that I will have to shuffle some things around, but I'll keep the capability the same. I do want to buffer the serial data as I've had issues in the past overloading the R2LC output data line.
