Hey, cool project. Lots of simpler inspirations obviously. Ultimately an extension is more friction than a web page, but it comes with much wider capabilities when you're not locked to a single tab. So it's the right choice for peerd in particular, but the web page approach for a low friction demo is a good idea. I have two small ones on peerd.ai (the real linux terminal, and the p2p connections) but can probably flesh that out more in a compelling way.
