I work on some BitTorrent software and while it's a really cool protocol, it isn't designed to sequentially stream data. Some clients support streaming, but the act of prioritizing sequential chunks of data rather than chunks that are most likely to be unavailable in the future is bad behavior for the collective group of peers. I haven't personally given much thought to solving the problem of streaming, but I am surprised that the WebTorrent FAQ doesn't mention why they didn't…

Does it mean that whenever I click on a link I must be afraid that my computer will start to participate in a filesharing network? What if a website uses the technology to spread copyrighted material in the background without me knowing about it? Maybe the website had a simple XSS hole that allowed an attacker to do it? So later I will get a fine for spreading copyrighted material and I don't even know where it came from?

Been in love with this tool recently. So helpful for transferring large files between friends/devices with a simple link.
