I saw some guy on a server once, and he put a wand in it next to an infusion altar. Not sure what that would do, but it's something.
If you could do that then the player who didn't place the stone could put a tablet anywhere and break through defenses.No, I meant having the "plug" be at the END of the tunnel, not completely bordered by the actual walls; the first tablet would be on the ground, while the second would be up on a block:

XPT
TPX
It's a moot point, though, since wands in a TDT apparently can't remove phantom stone blocks. Shame, that.
