I'm going to reply to just the one poster, as explaining this to each /.'r would take rather a long time! :)
First and foremost, Slashdot (as you know) unfortunately chooses the URL for your particular story. "Truer[sic] Randomness" is not in fact what I'm going out to somehow magically solve (with my absolute non-background in cryptography etc.). As to why they chose to enter the title of the story as such - I don't know. A bit of sensationalism, perhaps? In any case, I'd originally titled this "Musical Network Captures" - no more, no less!
Why not use /dev/random? It's not random per se which is required - it's a pseudo-random source which can still be directly influenced by those in the immediate environment. For installation purposes, for example, it's a quick (unorthodox, convoluted, fucked-up, whatever-you-wanna-call it) way of generating an input that can be used to further modulate other inputs/sounds. For this, a stream of random numbers alone is not good enough. There's a million and one ways this could have been done - it just so happens that this is how I decided I'd go about doing it.
Finally, I'm a bit overwhelmed by the whole Slashdot thing. As it's all worked out, it seems that on my first 'go' at adding something that I thought a couple of people would be interested in, it's seemed to hit the front page - and so at least, next time, I'll know to not be so trigger-happy when I'm 'submitting' something to here! Apologies for all of you who seem to have fallen out with one another and spent half your time bickering over nothing.
