Hidden device distorts news on wireless networks (with technical details)

I'm enjoying one of the comments on HaD, along the lines of "Let's configure it to tell the truth."<p>That's probably the most disruptive way you could use the thing.<p>Also, cross-injecting articles from sources of opposing bias could be a winner as well.<p>EDIT: Direct link to (very elaborate) build guide: <a href="http://newstweek.com/howto" rel="nofollow">http://newstweek.com/howto</a>

Can anyone comment on the legality of packet manipulation? What if you own the source providing the internet connection?

No mention of encrypted networks, so I'm assuming it only works on open, non-password protected network?

I'd like to have it replace the word "piracy" in articles with "copyright infringement". I think that would lead to a more balanced discussion.<p>Can you guys think of other words like that?

Love this idea. I actually had a similar idea a few months ago, but was planning to implement it as an email and web proxy that could be surreptitiously installed on someone's computer.<p>Rather than news sites, my proxy would tone down political vitriol and jingoism. I want to have it ready in time for the 2012 election season.
