Comment It's only 1 packet per second, even at 120 WPM (Score 2) 106

I actually thought of this.
XMPP real-time text is the world's first real time text protocol that encodes key press delays:

So even at 10 keypresses per second, even over a satellite connection (or other high-latency bursty connection), it only needs to transmit 1 packet per second, and the typing comes out naturally.

XEP-0301 (the protocol) is a packetization of typing including typing delays, much like VoIP packetizes short snippets of audio.
Explained in first section in section 6:

Understandable, but real-time text can be turned on/off.
Some users like, it and some don't. AIM has an enable/disable feature for Real-Time IM.
It can be an optional feature, like optional audio or video in their IM chats.
I'm a deafie, and it's beneficial to use from time to time.

However, add some LEDs and an infrared sensor, and you are left with an instrument which has improved pitch depth and looks impressive with in the dark. Oh, and you can control it by waving your hand."
