One gallon... hmmmm now that's a thought, especially if I wanted to go all grain. Which I really want to do and from the looks of it, totally possible for an apartment dweller like myself.
Ok storage... I'm not concerned about the equipment, but I am concerned about maintaining a good fermentation temperature. But I guess there's only one way to find out if it's possible.
As much as I am big on small batch brewing, a gallon (actually 3/4 of a gallon) is a lot of work for little payback unless you are making something like a barleywine where you will end up with only 4 bottles. Or trying to perfect a recipe before scaling it up, where you know you're going to be tweaking it through a few tests until you nail it. You will end up with only about a 6 pack of beer.
Most of my small batch brewing is of the 2.5-3 gallon AG batches, usually in the winter on my stovetop, using an unmodified 2 gallon cooler (which holds 4#'s of grain) or my regular 5 gallon cooler with braid, and either a mr beer keg, a 3 gallon better bottle or a 3 gallon water bottle.
I posted a lot of info in the mr beer thread, including recipes that you may find helpful.
The nice thing about doing 2.5 gallon recipes is that you can split any recipe for 5 gallons exactly in half (including hops) and brew it.

Many of those I show in there were done with an unmodified 2 gallon cooler. But you can do a lot bigger beers with a 5 gallon one. And a 10.00 SS 5 (actually really a 4.5 gallon) gallon pot I got a Dollar general.
One thing that is invaluable for stovetop brewing of ANY kind is fermcap s foam inhibitor. You can have you kettle nearly filled to the brim with a rolling boil and not worry about boilovers.
