"The 3DR radio firmware participates in the protocol stream, and it is controlled using AT commands. Any module interposing the conversation would have to be similarly aware. It's not a bad idea for experimentation though."

With the profusion of low-cost components available today, it's tempting to pick the cheapest one that looks like it will do the job and not stop to think too hard about how well it's going to work. After all, if it's for sale and other people are using it, it must be OK, right?

Michael Bro are you around? I was trying to see if you were still willing to ship me those OpenPilot boards you had. I haven't heard back in a few weeks... hope all is well. Let me know if I can PayPal you to at least cover shipping. STILL eagerly awaiting your response. 

Take care.
