Any one try anymeeting.com for video conferencing?
I have been playing with a free video conferencing website called Anymeeting on my playbook, it may have possibilities for some and worth a look.
Free Web Conferencing Software, Free Online Meetings, Free Webinar Service Providers
They have a non-registered user part that I could not get to work from the playbook, however once I registered for the free conferencing I could log on to the site from the playbook. I have tested it between my playbook and PC with good result.
