understanding intended use cases

Hi, this is a really great lib.

Trying to understand the intended use cases, outside of webtorrent. From the top of my mind:
- open and read a file locally
- send and stream a local file to another browser using webrtc
- open a file downloaded from a remote server
- render live some file while being worked in the browser (like md->pdf)

Most of the use cases are relying on ReadableStream from browser API, I think. Is some kind of bridge between nodejs ReadableStream envisioned? That would need more fined grained API (to handle precache for instance).
