Create 2 resources at the same time? Evolution

I have a duplicate resource of every page on my site. They have the same name and createdon etc, but, they use different templates.
The first one I create for my "regular" site, and fill the content manually. The duplicate is for the iphone version, which has a Ditto call to pull the content from the first page automatically.

I don’t want to have to do things twice, every time I create a new gallery or blog post.

Is there a way to automate the creation of the duplicate upon creation of the original, without having to manually create a new resource and input the information in all of the fields?

Sure. Use a plugin to load the duplicate page into the database; use the OnDocFormSave event. I think the POST will still be available to your plugin code.

I cannot right that code myself, hehe.
To further prove that, my next question may be totally uninformed:

If I use the OnDocFormSave event, won’t that make a duplicate each time I edit and save the document in the future as well?
What about a button or field that duplicates it when I am ready to dupe it?

I was hoping somebody might have gotten this done before.
