But what does it mean to "mount" a filesystem to a webpage?

Does the webpage have access to those files? Yes.

But then what's the difference of running a HTTP server?

Hmm....Commands over websocket, programmatic access via script, authentication inline.

I like the idea...it seems interesting.

What do you think? Would this be useful or interesting to you?

Background:

I just used SCP for the first time to copy a file between two SSH sessions happening in browser windows, and I made the above note to myself. I didn't know more about it so I thought I'd ask here and see if anyone has any useful thoughts.
