John,
Fantastic idea. My thoughts would be to house everything in the DB25 hood and
instead of having a cable hang out it it, just put a Micro or Mini USB jack.
That way whatever device you want to attach to can just hook up to it with a
standard USB cable. A MUCH cleaner solution than piecing everything together.

I'm still investigating Bluetooth options. Amazon's Bluetooth to rs232 options

Seems like we need a custom cable. It would be nice to have a cable had USB
OTG, USB Serial, DB25, and proper full-null wiring all built into one cable.
They make the FTDI chips pretty small. We'd also need a small PCB and the FTDI
chip surface mounted to it.
Even if we kept the "OTG" feature separate I think this would be really neat
M100 peripheral.
One could use a glue blob to protect the components or for a better look 3d
print a shell. 3d printers are becoming pretty common we could print some batch
of custom cases. A work friend has offered to print me some parts to make a 3d
printer, I will give it a shot if that ever comes through.
