Looking for a cost-effective web conferencing solution to show
powerpoint show for least cost as possible.  I've seen many solutions
like Webex, GoToMeeting, Breeze, etc., but those are far too
expensive. I need to hold 8 online web conferences, each of which will
have 200 people on it, all of whom will be viewing a powerpoint
presentation of mine. I already have a low-cost teleconferencing
solution, so now just need to find the web conference part. One avenue
is to use an all-you-can-eat, unlimited solution like
presenternet.com, but looking for more choices and hoping someone can
help me out. This is my first time trying to do this, and don't know
much about it. I am up to using any technology that works, so long as
my costs are minimized.  Would like to see at least 5 alternatives and
don't want anything above 3 cents/min.

Check out glance (glance.net) - I use this at work as a training and
support tool.  They have a 15 day free trial version available and
then two seperate tiers of usage, both of which are pretty reasonable.
And it works a LOT better then webex.

If all the attendees are on PC's, you may also want to take a look at
Meetingonnow.com it's the only one I know of that can accommodate that
many people per session without additional or per minute charges.
