How about a CD or DVD as a pad? Use a pseudo-random number generator as an increment for the next digit in the pad.
So the key may be based on a song, a movie, a you-tube video or even a Windows install disk. The pad would be generated by taking samples from pseudo-random places on the source file.
Voice is one place for stego, but Video over IP can use a lot more bandwidth, and gives you more places to hide info--you can do more with the codecs, and can "hide" information in the picture itself (hey, the bad guys could use sign language.):)
One interesting thing about the paper is that it implies that some types of DRM mimic stego. Is this a reason to outlaw DRM?

You're assuming the distance between samples is 1. I'm assuming its a pseudo-random number.
Yes, you want to generate the same pseudo-random number on each side, and use it to create an index into the source file for the pad.
