iMeet is a wonderful site for doing meetings or video chats on the web. At first glance this reminds me of Google+'s "hangouts". This is a visually stunning innovative site that allows up to 15 users at once. Also, there is the ability to share all types of files, text chat, etc etc. Keep in mind this is not a free site (free 30 day trial) but $69 a month.
