I wouldn't have thought that this would really be necessary. IMHO the chatterbox is just a quick way of getting some realtime(ish) communtication with other monks.
A different channel of communication (email/ICQ etc) would probably be a better medium to communicate embarassing/confidential information on.
I think it would be great to see different chatrooms/threaded conversations etc. but its probably beyond the remit of this site. A perl related IRC would be a better bet.
