There may not be a law for exporting the phone, but there are laws for data and data encryption. Abroad is only allowed 64 bit encryption I believe, or something like that. I'm trying to remember this off the top of my head.
So, as long as the internet feed isn't using an encryption level higher than what the US allows outside of the US, if they're using any encryption at all, then you're good.
But if you take that technology over seas and they begin to replicate it, I'm going to hold you personally responsible.
