In-browser discovery of local-network IPFS nodes

FlyWeb provides mDNS-ish announcements and discovery in Firefox. This sounds ideal for WebRTC signaling. Instead of fixed signaling servers, ipfs in a browser tab can announce itself to the local network for signalling. @ipfs/javascript-team where's the caveat, this sounds too good to be true. 😍 And it would make for awesome browser demos. Here's how I cut my DSL cable, and Orbit still works.

• https://flyweb.github.io/spec/
• https://wiki.mozilla.org/FlyWeb

My Firefox 51 here already seems to support it behind a feature flag.

We would still need signaling servers for more global connections though, right? But this sounds very intersting if we can use it.

Yeah this would be for local/offline cases

Another discussion about FlyWeb: ipfs/js-ipfs#599

Here's a few words from one of the FlyWeb devs on why it stalled:

16:29 | djvj | well, the maintenance stopped because there were some fires to put out generally in other parts of the codebase.
16:29 | djvj | Basically we came to the conclusion that the best way to push this forward was to go with a simple standalone mobile app (wrapping a WebView) that implements the FlyWeb client functionalithy.
16:29 | djvj | and then grow from there.
16:30 | djvj | But the whole quantum and Firefox desktop browser performance and QA effort came up right about then.
16:30 | djvj | So short answer: other priorities, not enough time to keep it running.
16:30 | djvj | pacer: if you want to do something with it, I'd be stoked.
16:31 | djvj | pacer: the apps (both iOS and Android) are available on our github.
16:31 | djvj | pacer: if you want to talk about what we had planned and why and what the general strategy was, that's cool too
16:32 | djvj | I still think it's a project with great promise, it's just that between work and new fatherhood, I don't have a lot of time to put towards this.

Multicast DNS API for browser extensions is being designed in mozilla/libdweb#7

That's excellent!! :D
