I have a skype and a poll everywhere account. I could see using these, but again, there are other tools that already make it easier through moodle. One that is developing is the big blue button. With this tool, I could teach my class from an off-site location, by my students logging in to my website and watching as I went through the lesson. I would be notified when they had questions and they can video conference and chat real time. It also enable me to make them the screen caster so they could share with others. This would be really handy for those that cannot make it to class because they are ill.
