WordPress as a web app - always auto-save post and meta data

Question

Is is possible to make WordPress auto-save revisiona more often and have the auto-save version always be the most recent version - Like the way google docs works. This would mean the update button is not necessary. you visit a post or custom post type, make your change, then click to another part of the admin, and your changes are always saved. Saving all the custom fields during auto-save would be essential. (maybe we'll see this in wordpress version 5.0 ;)

Here is my problem: i want to insert helpful links in post meta boxes linking to other areas of the admin, but I can't without putting a big warning beside each link telling the user to save first! any suggestions?
