There is a forum member called Entwined Scylla who has expressed the same approach for a portable minibog. Basically, a place like Home Depot or Lowes sells large, round planters and whiskey barrels that can easily be converted to a minibog. They also sell a product that which a planter sits on top, that is on wheels.
VFT's really do best when outdoors. They are not at their best on a window sill of terrarium, as many sundews and butterworts and bladderworts are. I live in the Buffalo area and what I do is use buckets with handles for minibog type plants - VFT's, temperate sundews, and American pitcher plants. When the temps are going to have overnight lows below freezing, I just tote the buckets to the attic, where it is cold, but not frigid, and place them by a south facing window. They stay there for the winter and I'll take them back outside when the overnight lows are going to remain above the freezing mark.
When you get to Georgia, you will be dealing with providing cold enough temps in the winter, instead of trying to keep them from freezing to death in the North. Many people in the South will get them as cold as they can outside and place them in the fridge for the winter. But more important than cold is photoperiod. People on the northern west coast may not get the temps to naturally go to freezing, but the decreasing photoperiod puts the plants into dormancy.
I had to pack my plants this past December, moving from Reading, PA to Buffalo, NY. For the VFT's and the rest of the minibog plants I just put the buckets into the trunk. They were already cold. The rest of the collection I put into the largest cooler Kmart had.
