make DistBB but in the browser, with WebRTC
all data = cookies

No. I consider those programs fundamentally broken...

welp, then just say that you don't have a modern browser and stop blaming me

and seems completely useless except for allowing you to make the statement ``I can do X without any downloaded executables''

When I say executables I mean independent ones, binaries you know
