That's what I thought of many times...

How about changing main.dtml with a series of diff-patches on Zope's 
startup?

- Zope starts and sets up the main.dtml as manage_main of the ObjectManager.

- Product A (e.g. External Editor) applies a patch to the source of 
manage_main (as diff to the "official" main.dtml)

- Product B (e.g. AbracadabraObject) applies a patch to the patched 
manage_main (as diff to the "official" main.dtml)

- and so on...

Some guidelines for Product-Authors should help avoiding interferences...
