Found a nice example of using Skype Prime for language lessons. Say it in Dutch Language School provides lessons over Skype in addition to their emails, ebooks, podcasts and summer courses. As they put it:

>As a Skype student you only need an internet connection, a headset and motivation.

It looks like they have a free trial, too. I just signed up for that to dust off my Dutch skills.

Update July 27th. I have tried out the Skype Prime Dutch lesson now (and realized how rusty my Dutch had gotten). The experience was excellent. I particularly liked that Yorien, my teacher, posted new expressions as chat messages as we spoke.
