Show HN: Tab Sharing Without Screencasting

Hi HN, I've developed a Chrome extension that provides tab-sharing functionality without the use of screencasting. The product works by keeping the DOM on a mirrored page in sync with the driver's display. This is achieved by listening for DOM events on the driver's page and relaying them to the mirror as display instructions (e.g. add/remove a node, change attribute, scroll page, etc.). While the mirrored page gets the DOM structure directly from their peer via a WebRTC connection, the bulk of the resources and visible content (e.g. images, fonts, stylesheets, etc.) are downloaded directly from the site being browsed. There are two significant advantages of this technology: 1) Because each peer is rendering the same DOM with all images downloaded from the same source, they see identical, full-resolution displays of the same web page. In contrast, screencasting over limited bandwidth connections often appears as jerky, low-resolution representations. 2) As the peer-to-peer messages sent to maintain page sync tend to be small, the application does not require significant upload bandwidth and can be more performant for users with slower internet connections. To check it out, you will need to create an account, link up with another user, and install the extension. Instructions for doing this can be found at https://ift.tt/2Byn4iK I hope you give it a try and I'd be eager to hear any thoughts, suggestions, or requests!
