Extradimensional Space in an Extradimensional Space, What Happens?

[jeff37923]

The spell Rope Trick has a note at the end of it which states that it is dangerous to create and extradimensional space inside of another extradimensional space, but it does not say what happens or why. The rules for mixing a nondimensional space and an extradimensional space are pretty clear (see both Portable Hole and Bag of Holding), but nothing about an extradimensional space interacting with another one.

So, what do you all think happens?

EDIT: I just read on WotC where Skip Williams recommends that this just be ignored. I don't think that option would be nearly as much fun as if something catastrophic happened.

Looped time and spatial folding are the DM's friend.

Whatever the plot and DM think would be fun. A rip in the fabric of time ejecting evil twin versions of the party would be fun.
Or shoot everyone to the astral plane.
Or a moon.
Or Inevitables appear.
Or an explosion that makes the caster lose the ability to cast spells for awhile.
Or when the exit the rope trick its in a vastly different part of the world, or an parallel universe world(the whole Sliders thing).
Or it creates a Gate from which invading armies start to pour through, and the PC's have to fix it.
Or nothing at all.

I'd say either all of creation immediately ceases to exist, or absolutely nothing happens.

Edit: In true Gygaxian fashion, which result occurs should be determined by a random die roll.
