Para que reunirnos físicamente si podemos hacer una videoconferencia compartiendo archivos, el "escritorio" de nuestro pc y dejarla grabada para después poder consultarla. Todo eso y mas nos permite BigBlueButton el cual les mostrare hoy como se instala y configura. Usaremos un server Ubuntu 10.04 (al día de hoy algunas dependencias aun no funcionan con Ubuntu 11.04 server)
La configuracion la haremos desde root
