F3 has some changes and additions:
lc:
b: Shows what biome you are in.
bl: Block brightness.
sl: Sky brightness.
rl: Raw brightness. Due to popular demand, Seed info is now "0" in SMP to avoid people recreating the world in SSP.
nothing special about the world, servers just don't show seeds anymore
Well Today 3/4/2012 Me and my friend Zombizap went onto his server and so he pressed F3 which popped that screen up and so we looked at our seed and it was 0. 0 no other numbers and other weird things happened like a sandstone well.
