Is it possible to bind StickyArea to Entities?

[FlawlessHappiness]

That was beautifully explained!
Ok, so I suggest you have the following entities:

Gas Bottle (static)
Hose (moveable)
Flamethrower (movable)
Flamethrower connected (moveable)

So I'm trying to avoid using sticky areas now.
You can script it so when the Hose and the Flamethrower collide, they will be set inactive, and the Connected Flamethrower will be set active instead.
