the idea really sounded great, but how will it look in practice ?
I think this also solves a problem of hosting small applications. Let's say you have a webpage a simple .html file with javascript and css inside the code, let's say 100Kb that you want to host somewhere. Cheapest hosting today is like $1/month? With btfs you can host your small application or anything for about $0.0000025/month for every 100Kb
