If you count 10MHz and up as rhythmic then yes! But kidding aside it would be really nice to have a musically encoded version of TCP/IP that sounds nice to the ear.
You could start by picking a major key and then dividing up all bytes to be transmitted into groups of three bits (have fun with the shifting...), that way all 8 tones get to be played, and since it will be monotone it should not sound too bad. Major points if you can do this with chords that sound harmonious.
