From the result of the poll (thanks everyone that voted), we now have a new world!!
The server is whitelisted to keep things safe until at least a Beta version of Bukkit 1.6.1 is released.
I'm taking requests for what buildings people want moved over into this world (I have the old one backed up). It is a bit of work to move things, but I need two things from you: What to move, and rough x, y, z coordinates in the new world. If you're fine just starting from scratch, all the better!
Once Bukkit is back, I'll be adding a 'Creative' for anyone who wants to use that. It will be normally generated (not superflat), which should provide plenty of nice scenery.
