Video Conferencing in the class room

Hi my name is Zachary Flanagan and and I work for Perfect Video Conferencing; we are a LifeSize reseller.  I am new in this industry and it looks like schools have really been utilizying this technology.  I am also a full time college student and have not seen it being used in my school.  Since this is a network of mostly teachers I would love to hear if you are using this technology and why and also if you are not using it, why not?  Thank for letting me be apart of Classroom 2.0 and Happy Holidays!
