There's a full-page an ad in my local newspaper today for web conferencing. It's aimed at biz fliers and makes the pitch that you can forget about jet lag and being away from your family because with a Web browser and a phone "...you can hold live, interactive meetings with up to 2,500 people over the Internet."

I also met someone who's involved with one of these companies who thinks that (or maybe hopes that) this is going to dramatically reduce the amount of business airline travel in the near future.

Business travelers, what do you think? How much of your current business travel could be replaced with something like this?
