This will ensure that as a community we will have already given an associated value to the coin through our IPCO structure.
Correct me if I missunderstood you.
You say that there won't be a wallet and source available until the IPO is completed.
So you want to say I haven't even a prove that this coin really exists until the IPO ends (after all 7 stages)? So you just playing with numbers like "Thank you for investing 0.5 BTC your stake of xxx CPL is documented"?
You have to admit that this will lead to a very risky investment, if you can't prove that there is at least a coin behind this concept.
And a suggestion to the escrow service. You wrote escrow would be difficult because of the buy backs. You could easily instruct a trustworthy member who offers an escrow service. The escrow agent could also run the buy backs for you.
