Sorry Jason, I should have been more specific (but I was off to
"RealLife(tm)" when I wrote the note).

With MeetingPoint and ClassPoint installed, you can achieve this:

An instructor, or moderator, can have control over the one or more
students, or participants, who are in the "spotlight." This give the
instructor the ability to direct who is seen by whom and who can speak when.

Orthoganal to the spotlight feature, the instructor can control the level
of chat in the conference. The instructor can choose three modes:

1) Students can chat to INSTRUCTOR ONLY
2) Students can PUBLICLY CHAT

Thus, using an instructor conrolled environment with chat more 1), students
would be unable to chat UNLESS they have been allowed to by the instructor.

The level of granularity (i.e., spotlight alos controlling chat) was
specicially decided against in ClassPoint 1.0, but may be revisited for
future updates.
