is there anyway to add ender pearl blockage? this would be very useful in keeping people out of areas that they could otherwise just throw a pearl over a wall and just tp in.

can do this now with the prevent-teleport flag.

Might be doable, I'll take a look.

this goes along with my recent issue - i think using a pearl to teleport into a jack-o-death field, will also allow the player to enter the field and not take damage (so long as they don't move off the block the teleported to) - haven't tested this with the pearl but i know it works with /home and /tp
