Installed it, and before I found out I had to select 'Terrain Control' as the world type, I used the default one twice, the generator must have heard my complaining, because it landed me in areas I had never seen before.
Oh, looks good! Thank you! (But it's a bukkit add on, so it's for servers alone, right?)
It's not bad per se, it simply lacks variety and is too flat, the only part which makes me awe is the big mountain biome which is kind of rare. And it barely uses the new height limit. It is already rare to see a mountain over y110 or so... :S
