If my understanding of the way the information is stored in the database is correct (and it might not be) the crossposting text that appears on your notDW entry is still treated by the Dreamwidth database as a separate object from the entry.
That seems to be correct.
You are, if I understand you correctly, asking Dreamwidth to create a template in your post, which will then be editable by you through the entry edit form but also by Dreamwidth's automatic crossposting software.
I would prefer for it to work exactly the way the LJ version works: when I hit "post entry", generate some text and include it at the bottom of the entry, and after that let me edit it the way I edit any other text.
I suppose that to prevent crossposting infinite loop hilarity, the DW footer shouldn't even be different from the LJ footer, but should say something like: "Read this entry on [link]Dreamwidth[/link] (n comments), [link]LiveJournal[/link], or [link]InsaneJournal[/link]." That footer works for any version of the post on any site, will copy over properly if I edit the DW entry, etc.
