If you're going to be traveling by air, you've got something of a paradox. On the on hand, you'll want to package the hell out of your brew to keep the baggage apes from smashing it, on the other hand, you'll want to make it easy for the security people to identify and/or inspect. If you can afford it, it might be worth packaging it like you were going to enter it in competition and shipping it separately.
If you're going to be traveling by car, just make sure that the beer is kept cool and that anything that could be interpreted as an "open container" (e.g., kegs, grolsch bottles) by overzealous law enforcers is hidden away in the trunk of your car.
