Re:TTY? (Score 1, Interesting)

My wife is deaf and I am hearing. I can tell you that there is a huge difference between using a system of IM/SMS/TTY vs using sign language. It can be basically summed up as the same difference between singleplex and multiplexing. With video you have the ability of bidirectional communication and faster throughput of words. Which is the difference between a 5 minute conversation to a 30 second one. My wife can type about 70-80 wpm, yet she can sign many times faster... Recently we had a VRS (Video Relay System) unit installed at our house, now I don't see how we could function without it... It is like getting broadband.
