One interesting possibility: assuming the format of this message is fairly 
transparent, you could have the MUC room cut out the bulk of the keys in the 
message such that each user only gets the key they need.  In such a fashion, 
the message bulk would only occur when sending, and never when receiving, and 
the server still never gets a chance to spy on the messages.
