My Membership site deals with very sensitive subjects

My Membership site deals with very sensitive subjects and privacy is paramount. I have not used the Chat plugin in the past because the chat window is accessible to the public, and a separate chat page just does not work.

I have been using a paid version of Chatroll because I can install it as a widget on my members only BuddyPress forum page and everyone who is logged in can see it and use it.

Is there any way that I can use this Chat plugin in the same manner? To be more specific, can I add a Chat widget to my BuddyPress forum page and not have it show up anywhere else?

Thanks,

JoAnn
