I'm sorry if I came off confrontational to your response, I didn't mean to sound that way at all. I don't believe I'm taking this to an extreme: this forum is for developing apps, I wanted to give a warning that you should consider other options if you want to develop real apps that need this type of behavior.
Sure, you could do it, it might be cool. I didn't mean to discourage that at all. And indeed, I'm certainly not refuting it, as I have done exactly this for some network experiments in a project I worked on a few years ago. So I am not at all saying you shouldn't do it, that it's impossible, or that you are wrong: I'm just saying you should think twice if you think your app needs this. Maybe I was off base, because the OP asked why this couldn't be done. I shouldn't say it can't be, because it clearly can, I'm just saying you should be careful...
