The demo plan is that I will:
A) connect it to a non-routable development side of the pool, so that the box is unable to communicate with the internet. I will then let it submit shares to the pool and I will have one of the getwork servers in debug mode and I will see what is sent out and what's sent back. As I found no evidence of any wireless communications on the board, and since the computer it's connected to will not be on the internet, it won't have any way of falsifying the shares submitted.
B) I will take a unit home that evening, disassemble and take more robust pictures. I will NOT be removing any heat sinks, however.
C) I will do further testing that evening on my own with a packet analyzer to see what packets are being transmitted, when and where they are going and coming from.
That's the plan as of right now, at any rate.
A) Sounds awesome. I had not given much thought to the idea of being able to falsify shares with remote means as well as onboard. Thats pretty thorough methodology you have detailed and for thinking of such possibilities.
B) rock on, the ones you've shown so far are not bad. They certainly give the impression that the PCB is not as cheap as one would think either. Any insight on the etched out portion?
C) very nice to hear!
Hopefully they toss a few units your way for your time. As excited as some are of the prospect of a review/demo it ultimatly only benefits them.. =)
Cheers
