[visad] conferencing with visad...what are the features

[John Carlson <carlson14@xxxxxxxx>]

What are the features of conferencing with visad?

Here are a list of possible features.  Maybe someone can
comment whether visad provides for these or not.  If not,
perhaps someone could point me to the right place to do
this in Java.  Thanks.
