I take your definition of "a coin dev" is some sort of coder/programmer, right? Well, "dev" is short for "developer" and developer means to develop or, in layman's terms, the individual or individuals that bring a coin into existence... existence being creating value through demand (as in NOT through coding). I believe you mean will he be able to solve the technical challenges inherent to the process of development of Libertycoin? I don't know if he himself will have that ability/talent. But I DO know he is way more qualified than anyone currently in such a position, to seek and get the best help as needed. In other words, whether or not he is the "whole package" he is indeed the best package out there to be able to take this coin to the top of its possibilities.

Furthermore, I believe that if he is not fully able to do so, it is in his interest to decline the proposal.

Needless to say, I fully expect not only he will take the challenge but resolve it brilliantly.
