The server side should be working. The code is very example-y though. The authentication to the socket has been ripped out for now. needs to be implemented. guh.

I was trying to test the webtransport connection in the browser. it cant connect because of self signed cert issues. there seems to be a way around this but i wan not able to get it to work, so maybe someone smarter and more dedicated than me can. otherwise you might just be better off obtaining certs signed by a trusted CA and using those. id have to modify some of the server code to accept dev and prod certs in different ways. guh.
