Yes, dividends will be divided among shares.  The total number of IPO shares hasn't changed either.

I don't know whether or not this will eventually provide a good return on investment.  I was just responding to your original post where you were comparing the cost of rigs.  Tawsix said his rigs cost $1160, and you said you would spend $1200 to buy your own rig.  I guess that makes SIN rigs cheaper (you didn't give rig specs).
