Osage, maybe you could see if you're wife will train the wee beastie as a pack animal?
I almost got a pygmy last year with the intention of trying to train it for packing, but decided against it as I wouldn't have time for training (and the idea of a hunting MTB was more attractive). It would still be great to have one as a hiking companion though.
SquirrelSlinger, from what I've read, they will graze; but maybe Osage can give us some first-hand experience if we can talk him into training one ;P
