• PHP Code:

  set_task ( 0.1 , "ShowHud" , id ) 

• Why? You're displaying the message for 12 seconds. There's absolutely no reason to reshow it every 0.1 seconds. Also it will look really silly with director hud messages, because they have no channels and they will just overlap one over another so after those 12 seconds you'll have a big nice block of color if the content of the message changes a lot.
  
• Also, cache the hud sync objects.
  
• In GetName, check if the user is connected to the server. You don't even have to use this, just remove it entirely and get the name directly in the HUD function, just cache the bomb ent ID.
  
• Also, instead of copying the contents of dhudmessage.inc, just leave it in the includes and point to it in your thread in case it gets updated or something.

I didn't look thoroughly but that's what you should start with if you want this to get approved.
