Good idea but then idiots in the realms could go on a tnt rampage so you should be able to toggle tnt on certain people

Here's how I see it:

Option 1:
Everyone can do whatever they want with tnt, obviously the server will implode, so no.

Option 2:
Intelli codes it so that there is blah rule and blahblah rule obstruction people from lagging, but probably too much coding, not to mention strain on the server.

Option 3:
It's placeable but non-detonable, which seems like the best option to me.

I didn't realize that it wasn't placeable. i know it used to be, i blew up some invaders into a nether fortress thing that my town had made. I think if people really want TNT to be fully usable as in SSP, they should donate a bunch so Intelli can get a better computer As for the realm problem, I don't see why it couldn't be modified so that the explosion could only affect that which was in the realm it was placed in. Or, perhaps, it would count as block damage by the person who placed it. I think that the last is a viable idea for TNT security. It should definitely be placeable, though, even if only for decoration.

TL;DR: It should be placeable for decoration purposes, and if enough money was donated for a better comp for Intelli, then it could be coded to accommodate for security.
