I've been trying to figure out how to access my Pick environment from anywhere without having to install a terminal emulator or having my ssh keys available and finally got all the pieces set up.
Hopefully someone else finds it interesting as well, you may not be able to copy my steps one to one but it might give some direction.
You can expose terminal applications using gotty and so what I did was use gotty to expose scarletdme and then used nginx to protect the exposure with ssl certificates.
More indepth explanation with all the configuration files that are needed:
I think it might be possible to trigger downloads and do some fun stuff where you mix BASIC and web stuff directly. Something like typing out LIST ORDER.FILE and having a table appear on the web page in addition to the terminal window.
