Can you administer help???

I have a really good idea (IMO) for a module that I may consider building if something similar does not already exist. So far I haven't found anything that does this...

I will be handing off a relatively complex site to the end-client very soon. I have broken down the admin section so that the users managing the site will only see the pages and links that are necessary. Now I would like to take it a step further and add help text to forms and pages where necessary.

Currently, help information is provided in modules. It would be nice to have the ability to quickly alter or remove that text through a textarea or similar. This would give the site builder an easy method for adding instructions and notes to the admin section. Site admins could also easily do the same on the front end.

The module would allow you to:

• Add/Edit the Help Text for each page
• Add/Edit form field text including titles and descriptions

You can also display different information to different users/roles.

I could go into a lot more detail discussing the bells and whistles but this is the general idea of what I am looking to do. If you are interested in something like this let me know and share any ideas you may have. If you know of something that already does this or something similar even better!
