the purpose of the custom script -> viewer channel would be to avoid 
that "$init$..." message to display at all to non-custom viewers. An 
alternative could be to change the standard viewer to hide llOwnerSay 
that starts with @ or $. In any way, looking for something cleaner that 
is fully transparent to users with standard viewers and already existing 
viewers.
