The conference system can allow attendees (when logged in, and roughly during the talk time) to enter questions for the speaker. The room host can pick from the questions and ask the speaker to answer them.
After the talk, the speaker can optional enter a written answer to every question, even the ones not covered in the talk.
After the conference, the reference to who asked the the question will be deleted, leaving it as an anonymous question.
Questions stay up on the website along with the talk.
