I actually think that not only should it be in the database but that the database should be populated over xml-rpc.  Why?

CivicSpace, Development Seed, Bryght, Bloggers all have different target audiences.   We should allow for the complete customization of admin/help documentation.   This is similar to the system module which allows for different site directories to be created with an XML-RPC call.

Imagine if you will you are a small independent contractor and you get a call from a client saying they can't figure out how to use taxonomy.  Change the admin help documentation on the source server and tell them to go to cron.php.  POOF instant understandable documentation.

Of course, if I a patch doesn't get submitted to add this functionality in the next 72 hours or so I am going to go ahead and submit all 60 module admin help patches to head anyway.  :-)

Cheers,
