Have an old Bukkit server you want to run SpongeAPI plugins on? Announcing Bukkit2Sponge, a new implementation of the Sponge API as a Bukkit plugin, now available:

GitHub GlowstoneMC/Bukkit2Sponge An implementation of SpongeAPI for Bukkit servers (Glowstone, Spigot) - GlowstoneMC/Bukkit2Sponge

Bukkit2Sponge is essentially the opposite of Pore, in that instead of allowing you to run Bukkit plugins on Sponge servers, it lets you run Sponge plugins on Bukkit servers.

This project is in its early stages, not much is bridged yet, but I’m posting about it now to gauge interest and invite interested users to help out or provide feedback. At this point, SpongeAPI plugins load and a handful of events are implemented.
