Block translocator in volume?

[Virance]

For a map I am currently working on things would play out significantly better if the translocator was not usable in the flag room (and one other, neutral room).

So, two questions:

1) Is it possible to create a volume of some sort which prevents the translocator from working inside it?
2) If not, is it possible to just disable the translocator for the map?

I was wondering this myself. I also want to know if it's possible to make a static mesh block bullets as well as translocators - but not players. Because I have a flag room that is unreachable by foot but it has a force field thing at the door, so the only way to get into the room is by jump boots.
