Your points are valid and well taken. I am open to suggestions.
The easiest answer that I can see is to stick to a 1 Raspberry Pi to 1 Bitcointalk account paradigm. This opens the door to allow the same person with multiple accounts AND multiple Raspberry Pi's to gain additional initial stake equity.
Part of me says, 'so be it'. It is the simplest solution, and requires a larger commitment.
What do you guys think? Is there a good way to solve this problem? Is 1 Pi to 1 account fair?
I don't have any suggestions because Im not an expert in such things I just want to add that this issue will also affect students in dormitories because I think that they all have the same IP. At least this is in Germany the case.
Maybe it is best to the use the described paradigm.
