Home brewers have been bottle priming with table sugar as far back as prohibition. Last time I had about a gallon that would not fit in my keg, I used I believe two of the paper sugar packets per liter flip top...beer carbed nicely...I ran the numbers based on grams in one packet and vols co2 desired, worked perfect!!!
Back to the OP, yes I am a believer in kettle fermenting, surprised more folks don't try it! It is incredibly easy and effective!!!! Ask a lazy man!
