How can one user download a file from another user's computer through a website?

I want to create a web application in which one user leaves his computer from a website and another user can download a file from his computer. The user will need to specify which file they would allow to download from their computer, but it should be completely between the two computers. A user who leaves his computer will look like a server to other users trying to download it. I do not want my own servers to handle all traffic. In addition, all this should be through the website, not the program.

A person leaving the computer will see a page with a status bar in which how many people are downloading his file, and he can click the cancel button at any time so that people can’t access his file.

I saw something called a "flash-java-socket" ... Can an attempt to complete my task?

There are several obstacles:

  • Web pages cannot accept incoming connections
  • Browsers do not allow you to access the file system (well, traditionally)
  • Most users use NAT behind the router, so you need a port to access your computer.
  • Changing IP addresses is slightly larger than others.
