Hot Topics for Tech Talks?

HCIGuy asks: "A few of us are working within a local school of engineering and technology to set up a seminar series unique to the area. We envision a sequence of monthly seminars that focus on bleeding edge technology, presented by vendors' engineers, and attended by students, faculty, and industry folk. No marketing hype allowed; we want only the facts. We obviously want this to be of high interest to everyone, so we're asking for input on what topics would be of sky-high fascination right now. What would it be? We're leaning toward wireless for our first program, but all comments gratefully received. What topic would make you rush out and drive across town to hear it? We have only an hour and a half to commit to this, so the material has to be narrowly focused. We plan on holding up to six per school year, and we don't intend to hold over subjects from one time to the next."
