Tunneling Internet traffic over FB chat
I think this is kind of abusive of FB's infrastructure TBH.  It must be hard to keep real-time messaging up for ... okay, I was going to say for 1 billion users, looked it up and it's 1.3 billion monthly actives - 890 million daily actives (Jan 2014 figure).  So tell you what, on second thought I think they can handle your data.<p>however there's a good chance you'll cause some infrastructure problems since I'm sure there are assumptions baked in, regarding how often a user will send new messages, queuing, caching, etc.  so I'm still not totally sure how I feel about this.<p>at the end of the day FB is just a php script.  i wouldn't be surprised if you break it.
