I've shipped long distances quite often (I live up beside Alaska actually, and regularly we haul to BC or Alberta - up to 24 hour hauls).
If you stop often to allow them to rest (they can even stay in the trailer! We try not to unload, as often we're hauling 8 or more horses some of who don't load very well), it's not an issue. Bed deep, offer water (though ours don't eat or drink much while hauling).
I am possibly hauling my mare from here to Manitoba this summer (so like 40 hours or something) and for that one, I'm probably bringing portable corral panels that I can set up alongside my trailer for overnight stops.
Your choice on whether to use coolers/travel boots/etc. We never do.
If it were me and I had the option of buying a truck and trailer, that's what I would do. I've known some excellent horse haulers, but also heard not so good things about others... and I'd rather not trust my horse to anyone.
I'd also stay away from ferries if you need to be on for more than a day at a time. Besides the stress of being on a boat, I can just see the mess that a horse in a trailer on a ferry could cause :S even WITH cleaning the trailer. Plus, ferries are expensive if you take a vehicle on (from what I remember anyway!).
I'd never consider flying a horse purely for the shipping cost.
