Quoted from vid1900:
The unrefrigerated beer in the lines would quickly get warm, so you would always have to "let it run" to get to the cold stuff.
Also - beer turns to foam at 40 degrees. It's more trouble than it's worth to try to use it remotely.
Also - check the price of kegs where you live. Here in SE Wisconsin domestic kegs have gone up to $92 - or 4.6 cents an ounce. I can buy 16oz cans for about the same price. The keg has foam/waste, needs CO2($), and will go bad in 30-60 days. Cans stay fresh much longer - with no waste.
If you prefer draft, it might work for you. If you are doing it to save money, it is going to depend on where you live and the cost of a keg.
