A mechanism to post these sorts of documents exists on this server, as there are some LearnNavi documents updated this way. This is an excellent question for Insgive, or if you can catch hjim, Lajaki.
But yea, this is a really good thing to have because the wiki is not fun to navigate when you need to locate something quickly, or do it offline. And if you are willing to commit to keeping this up to date, I'll drop my plans to create a document like this, and concentrate on keeping the dictionary up-to-date.
If worse comes to worse, I have a place this can be hosted. The challenge is making it freely available to you for when you want to do upgrades.
