Yep, you're right. But the patch is not really defaulting to port 80 or 443, it's more like a "fallback" port if window.location.port is empty. window.location.port still have precedence.

Yep, again. In my setup, we don't want to expose the websockify daemon on the internet, it is hidden behind an Nginx reverse proxy. Nginx listen on port 443 and forward all the HTTP traffic to the right backend based on the content of the HTTP "Host:" header. The websockify daemon runs on a dedicated VM with a dedicated hostname.

Exactly.

I'm concerned that setting port 80/443 as the default may be misleading
to the average user.
In general, the port we need to specify is going to connect to a
websockify daemon, which will relay it on to a spice server. And, in
general, that websockify instance will need to be running on a port
*other* than 80/443, as 80/443 is usually consumed by a web server.
I realize that you may be proxying the port; I'm not very familiar with
that process. Is this a protocol proxy? That is, will nginx and/or
Apache intelligently relay a ws:// protocol request to an alternate port?
Cheers,
Jeremy
