Yes, but for people overseas there is the cost of an overseas phonecall. If the seminar is accessible via the internet, it would be different. So , in my opinion, making a correlation between phone access of an event and possible access through the web may not be correct.

I do not see all these technical difficulties when sites like KarmaCafe, Linda Pannell, etc make interviews via the phone available within 24 hours from the event. They do not charge for the services.
