I've installed Minecraft Server 1.4.7, Forge 6.6.0, BukkitForge-1.4.7-85 in "coremods" folder
And after loading world I get never ending spam in the console:
UPDATE: BukkitForge-1.4.7-26 seems to launch fine, with no errors.
But using Thaumcraft 3 "Wand of Excavation" on regions, which doesn't allow to consctruct, use and so on (with WorldGuard 763-7b435f9 for 1.4.6/7) breaks blocks.
So, I suppose, this all has not much point, if people want to use ForgeBukkit+WorldGuard on servers with mods to protect the land.
Otherwise, they can use just Bukkit.
