Microsoft Office Live Meeting is a conferencing service that allows you to hold a virtual meeting with small or large groups of participants. Live Meeting allows participants to exchange information via live video and audio interaction, chat, shared files or desktops, and pre-recorded presentations. Presenters can receive real-time feedback from meeting attendees to allow them to adjust their pace and content. You can also launch an ad hoc Live Meeting session from within Office Communicator. You can even record the meeting real-time and save it for publication over the web.
