Where should I incorporate my web design business if I plan on traveling and moving frequently?

I’m starting a web design business, which I’d like to incorporate as an LLC. I plan on moving in the next year, and I also plan on doing work for my business while traveling overseas for extended periods.

My question is this: is it OK to incorporate in a state in which I neither live nor work? Most of my dealing with clients will happen exclusively online anyway, so traditional state boundaries seem kind of irrelevant. I was thinking of incorporating in the state where my parents live, and listing their address as my business address. This way I wouldn’t have to worry about keeping things current every time I move or travel. Is this a good / legal solution?
