Both llTextBox and llFloaterHUD 
(http://wiki.secondlife.com/wiki/LSL_Browser_HUD) have one flaw, IMHO:

they use the existing chat channels (which are all public) to pass 
information back and forth. Given that a HUD can only be used by one 
avatar at a time, it seems worthwhile to implement a set of private HUD 
channels that offer a direct HUD <=> client connection without 
rebroadcast to the rest of the sim. A given HUD could reserve one or 
more channels that can't be intercepted by other prims/avatars, thereby 
providing a greater level of privacy and virtually no chance of spoofing 
the server or client unless you have physical access to the network 
connections.
