I would be HIGHLY interested in this for two of the main reasons already mentioned. To get more out of the specialty grains you would use in the process in my mind would translate to better flavors in the beers you would be brewing. Making it economical to do even makes more sense.
Time constraints. 10 year old son, 2 year old son. God help me. (at least the youngest wants to help me wash bottles.) Along with SWMBO taking night classes...
Time be precious in my land... But again in my mind, the extra time is worth the better tasting brew...
So who's the guinea pig? (I can't, I don't have time right now...

)
It's a superb idea.
