[Harry Potter] Is the taboo on Voldemort's name a great tool to weaken the deatheaters?

with the taboo in effect to summon agents of the dark lord to the location of the speaker, we can know when and where a group is going to be.  This sounds like a brilliant opportunity to lay an ambush. How effective would saturating the environment where you know a death eater strike force is going to be with large numbers of IEDs rigged to go off as soon as they apparate in.

Note that they don't just appear on the Trio's table immediately after they say the name- it takes a while. Presumably, they apperated nearby and scouted the area.  


Basically, they're not stupid. You could use it to lay a trap, sure, but it would have to be cleverer then "dig a big hole and yell voldemort in it".
