The licensing of the Bukkit Project is currently as follows:
Bukkit - GPL with NO exceptions
CraftBukkit - LGPL
Before you say anything we are aware that using the GPL will force plugin authors to GPL their plugin too and are considering changes to our choice of licensing. Though this has no legal weight, you can be rest assured that we will NOT be forcing people to GPL or open source their code and are looking for the best licensing for us to use.
Once we've looked into this issue enough we'll be announcing our license choices - and our license WILL likely change from just the GPL, but until then the Bukkit is under GPL with NO exceptions (this is not due to us wanting this; I am clarifying that we have not specified any exceptions on the license we've currently applied to Bukkit) and CraftBukkit is under LGPL.
When we originally decided to announce Bukkit, we were hoping to get some early feedback on how things should work and what we should be doing. Suffice to say, we've gotten more than enough of that thanks to the GREAT support shown by everyone within the Minecraft community! We completely understand that everyone is worried about whether or not Bukkit will be a good replacement or an improvement on what hMod has offered you in the past and are hoping to address any questions you may have as soon as we can get to them.
One of the more pressing questions we've gotten from people is a very important one that we'd like to address now:
Q: When will Bukkit be ready? A: We're pushing very hard for a preview releases within the next few days. This type of release will only give you a SMALL taste of what Bukkit has to offer but will be a working build everyone can play with.
Once we have that out, the next step in our roadmap will be to get a fullly functional...
