How does it do wget, etc. without violating CORS? I was able to download from a couple different websites.

It uses a proxy. JSLinux emulates a network device and sends ethernet frames to a proxy via websockets. The proxy sends these frames to a Linux TAP device. The rest is a decent firewall configuration.

You might even be able to connect to another emulated JSLinux machine if you know that IP address.

Yes it is possible. It uses the websocket VPN offered by Benjamin Burns (see his blog). The bandwidth is capped to 40 kB/s and at most two connections are allowed per public IP address. Please don't abuse the service.
