I doubt you will have time. I imagine that the moment the nether opens up, every large realm is going to be organizing teams to strip mine the whole place as fast as possible. There won't be any glowstone left after 48 hours have passed anywhere in the nether.

Well that depends entirely on how big Intelli sets the nether to be , which at the moment would just be 375x375 (very small area).

so 48 hours seems very probable, if Notch does not resolve the issue of world construction then Intelli will be forced to increase the size of the surface world to increase the nether OR have some kind of teleportation straight back to spawn if you build a gate that leads to outside the surface world.

you mean 750x750, 6000/8
and if the nether border was bigger, I think glowstone would be gatherable, just go outside x-z 375.
and then we remember how hard the nether can be to navigate vertically...
plus, if notch updates the nether, then glowstone MIGHT get cheaper.
