I think one problem there is that a lot of places block other ports. Was that not why websockets runs on http ports?

Websockets have to be careful not to enable a client-side SSRF by accessing anything you couldn't already access with an <img> tag. They can use any port except the ones that are generally prohibited for browser HTTP requests, such as 25 and 6667.
