Can luwak coffee be farmed?

Luwaks do not scoff every coffee cherry on a tree, they appear to be quite selective (which is very likely one of the reasons kopi luwak is so good) and only choose particular coffee cherries while leaving the vast majority uneaten.
I personally kept two luwaks as house pets for several years and, of course, I tried offering them coffee cherries. They sniffed their way through a number of large tubs of seemingly perfect, ripe, juicy coffee cherries however after sampling one or two, the remainder were treated with disdain.

My conclusion is that luwaks cannot be farmed with the intention of producing kopi luwak on any kind of commercial scale. I am skeptical of any claim that it is being done.
