As a "reverse engineering hacker" who is a diabetic with one of these pumps (The 670G to be specific) I have black boxed the shit out of it, but because it is doing a good job of keeping me alive and the cost of a new one is high I have yet to disassemble it and do a thorough RE of it. In ~4 years when the warranty is up an insurance is willing to replace it then I will be disassembling it and hacking the shit out of it.

What happens to all the pumps that break? Chances are that the mechanics break before the electrics, so there will be a bunch of broken pumps with intact electronics somewhere in the wild. Can they be had as freebies for reverse engineering? Many would get returned to Medtronic under warranty, but there would be exceptions?

I had one mechanically fail this summer and my options were turn it in or pay $3,600 and as much as I want to RE it I don't want to spend $3,600 on it. So far medtronic is doing a very good job of limiting the secondhand market on these. I do make regular ebay crawls looking for them through. so far nothing has really turned up :(
