How to develop and deploy add-ons for IE 11

Question

can someone answer any of these questions?

1. Is it possible to develop an add-on for IE 11 with access to networking APIs (UDP/TCP sockets)?
2. Is there any website like Chrome Web Store for publishing add-ons?
3. Is there a way to install an add-on from a webpage?
4. Would it be the same IE 11 add-on development and deployment processes for windows phone and windows desktop?

Thanks

By default IE add-ons have very limited rights but you can elevate it, as I understand. Some details are here. And take a look on this project, it can be relevant.
