"TechnoEd" isn't bad, but for smoother pronunciation, I'd reverse the components. How about EduTech? (Or, on a lighter note, EduGeek? Of course if you choose a quasi-slang term, you're running the risk of its slipping out of use...)

Whatever you choose, you need to research it to be sure no one else is using it. Then, after you've done business for a while, you can register it as a trademark.
