I refer to other posts on business applications.

Could it be possible to get displayed an icons/photo for each
person (also telephone user via Skypeout) - and make something
moving/changing within the icon/photo when the actual person speaks ?
For example, if there is a photo, the photo could be displayed more clarely
than the others (and blink ?) when the corresponding person speaks.

My point here is to get visualized (and see the name of ?) whom is speaking
within a conference (if it is a larger group - I guess there soon will be possible
to have a conference with 20 people and more ?).
