This week, thanks to Twitter, our audio comes from Alec Couros' Ustream video of a professional development session. Alec takes highspeedconferencing, CamTwist and Skype for a testdrive, with Kyle Lichtenwald, New Zealand Chrissy, Donna, Lorna, Lisa, Kelly and Jethro Jones, and Susan.

Alec also blogged about the experience.
