BYG: it appears that the goal is to reach every jew. today they may not be in kenya (or anywhere else outside the us and canada) but who knows what tomorrow brings. 10 years ago no one imagined a chofetz chaim in sin city but alas today it is there. it is a commitment and dedication to a cause (albeit a beautiful one, if you ask me).
further, so long as he continues to learn in chofetz chaim there will always be the chance that even after 5 or 10 years he will look to move to that location. There is no way of ensuring that you will stay in NY or any other large jewish city unless he does not plan on staying in chofetz chaim.
Joseph: I will not address your question because the topic seems to be limited to shidduch related questions. see, also, lilmod ulelamed, above.
