A website called Joker lets you stream torrent files from your browser without downloading the whole thing. This means everybody who downloads Game of Thrones will an even shorter wait period between the show airing and finding out where Daenerys put those dragons.
For serial streamers, this is a little slice of pirate heaven. That is, until it inevitably gets shut down. This is similar to Popcorn Time, aka the Netflix for torrents, which lets you stream torrents...but Popcorn Time lets you choose from a list of torrents, while Joker leaves it up to you.
Popcorn Time has gotten squashed and resurrected a number of times, but this is taking the streaming torrent concept even further and I can't imagine it'll have an easy time staying up and running (unless, of course, it's an MPAA honey pot, in which case, don't say I didn't warn you, here is your warning, do not use, caveat streamptor).
Right now, Joker is working well with popular torrent files. Teenage Mutant Ninja Turtles took just a few seconds to pop up. I tested a less popular torrent (an episode of Cougar Town with two seeders). I still have the page open that says "working" but it's been a while and I'm guessing it's never going to work. So while Joker says you can stream any file, it looks like they have to be fairly popular to actually play.
It's not clear who is running this site. There's a privacy proxy cloaking whoever is in charge when you look up the domain owner, probably because this is getting into some murky legal waters.
