There may be another possible option to teleconferencing.  Software named
"ICQ" may be another consideration.   I've been using it for about 10
months now, so far still free.   It provides for 'chat' sessions with
friends, family, et al, when by chance they should happen to log on
simultaneously.   It facilitates file transfer by 'drag and drop', and a
host of interesting features.

If an appointment is setup in advance, it would be possible for a number
of people to log in simultaneously for a group chat session.

ICQ is an interesting piece of software, and it can be downloaded from:

Something to consider.
