Freezing Bread/Pizza Dough

I've heard of being able to buy frozen bread dough in the supermarket, but haven't seen it.  It made me wonder about freezing pizza dough. 

I have a pizza dough recipe I love, but it makes way too much for one person (my daughter recently moved in with her boyfriend).  Would it be feasible to try and freeze half the dough for another time?

I freeze actual baked bread all the time.  For raw pizza dough, maybe bake it half-way (par-baked) and freeze.  That's how most of the supermarkets (even Whole Foods) get their 'fresh-baked' good in from the warehouse.  They then just finish baking them onsite in their own bakeries.

I heard something last week about freezing dough - the problem is that the freezing kills the yeast so probably best to part-bake as suggested.

I've freezed dough, after I've let it rise, but never used it to make a pizza base, only to make garlic knots...
