Inviting Digital Visitors in the classroom with Video Conferencing tools

A friend and former co-worker of mine recently invited a professional musician/friend of his to listen to and offer constructive advice to his middle school band students via Skype.  She listened to them play while he and his class appeared in the lower right corner of the screen.

I remember showing his how to use Skype years ago, and I was excited to watch his archived video of his Skyping experience with his class.  I am hopeful that as the new school year approaches, that more of the teachers at both of my schools become more interested in video conferencing using Skype, Google Hangout, or other similar tools.
