Forum OpenACS Development: autosave feature for xowiki

I would like to place forth a plan that we have at Solutiongrove to implement autosaving when users are editing xowiki pages.

I believe this can be achieved with some javascript with ajax. A javascript function will execute every n number of minutes where n can be specified in the xowiki parameter. The xowiki page is then submitted in the background with ajax to create a new revision.

So autosaved content can be viewed in the Revisions page.

I understand that the number of revisions can grow to a big number so I intend to keep track of autosaves in a separate table and create a sweeper that removes them (delete the revision) after a certain period of time.

What do people think about a feature like this ? Is the above a good implementation ?

Thanks,

Hamilton

The WYSIWYG editor the wiki is using is called xinha and it's a lot of javascript that needs to get loaded as the edit page is loaded. On firefox and IE I get a little delay as it tries to fetch all the icons and stuff.
