The aim of DeMod is to add something, that tech mods don't have, but what would nicely work with them. It's hard to say anything more now, because I have lots of plans. And I'm not sure which those plans I will really make. 
  
But one module is coming for sure. Let's see later what it will really contain. All I can say for sure about it: related to sounds. 
  
Status update 25.11.2012: 
I will publish mod when MC updates to 1.5. Before it, I will use time planning it. 
Confirmed and already started features: 
- Electro Mechanic Siren (DeMod: Sound)
