I see gemini as something that has the potential to be a big hit over
Tor, where people run local services on their home machines. In this
case, SSL is redundant and it's kind of a pain to deal with.
But there's really no reason one couldn't just use file:// or even
http:// I guess.

I am not sure what is the worse that can happen, actually. Messed up
screen is not necessarily the only possibility.
You could move the cursor around, or send the persons terminal into an
alternate character set (which really makes a mess). You could send
escape codes that put the terminal into tektronix mode, annoying
blinking text, things like that.
If the person on the other end were using a genuine terminal, with a
printer attached (I've used those, believe it or not!) you could poison
someone by sending the escape code to initiate printing. I haven't seen
a terminal that "prints" that way in many, many years. You'd have better
luck sending a zmodem transfer sequence and tricking them into
downloading files. :-)
I found a capsule that uses ansi extensively, and I'm quite impressed!
Check it out:
They're using it in ways I hadn't thought of. It worked pretty good for
me, except they're trying to emulate a slow modem connection which just
makes the pages take a while to load.
I'm impressed!

There is also Viewdata, which I think is similar. There are some Viewdata
services existing that you can access over the internet, and you can use
a Viwedata client to access it. It is a interactive protocol (similar to
telnet), unlike static pages that were previously used in television.
That would be pretty cool to see :-)
I've seen quite a bit of cool terminal stuff lately. Modern unicode
terminals hold a lot of promise.
Overall, I am impressed with gemini, I really like the design goals. I'm
happy to see someone actually is using color. I'm off to see if I can
find anything about viewdata protocol next. Thanks for the tip.
