Mob spawning in the nether

With the nether update being released, we have all of these new biomes, blocks, and gorgeous atmosphere which would make for an awesome nether base. However, in survival you're not actually able to build anything or live in the nether.

Sure, you can build.. But due to the mobs in the nether ignoring the light level rule, you'll end up having nothing but frustration dealing with mobs. You can light up your build as much as you want, but it will be full of mobs trying to destroy the place and ghasts spawning in, or outside of your build essentially making you only use the nether for mob farms and resource gathering.

We need mobs in the nether to either follow the light level rules so we can have freedom to actually build in all of the new biomes, or have some other alternative than only building in a specific biome and wearing a pumpkin on your head with matching gold boots.
