That's correct, Angelox. The first person in would determine the level range of mobs. One smart thing to do for power leveling was to get the highest to go in first. If you were farming smithing combine parts, you sent the lowest in first or if you were just farming instances you sent the lowest in first. I remember getting several groups as a 65 with a few 50's just so we could power through the instance and get the augment upgrade.
Spawning a dungeon based on character level would be easy enough and could even be managed with a PERL script. Just get $ulevel and then use a spawncondition to alter the dungeon.
As to the drops, certain drops were universal. Many of the trash or tradeskill drops were consistent across all level ranges and were a fairly reliable source of income for lower level players working their way through and selling that stuff to people working their smithing. I remember several mobs dropping similar level range items. For populating the mobs, you may end up looking to Magelo and Allakhazam and having to do a manual population, as much as that sucks.
