calculate Diff @ server, make DOM calls on client to reflect changes on mirror document also, how to

[Gill Bates]

so DOM calls should be calculated from Diff.

Possible?
How? (some URLs please)

I guess this is in most cases not very efficient, but here's why:

I have a data Document at the server.
From this document, views (HTML, SVG, GIF, etc) can be generated and sent to the client. These views contain Script that let them suggest changes to the Document at the server. If these are accepted, updates are sent to the views to reflect them.

Of course it would be ideal (for the user) to manually code an efficient function that reflects the update, for every kind of update and every kind of view. But the project would then not even come to a nice "proof of concept". Therefore first i want to implement these functions as mentioned above, making it easy to override them later.

Feedback is very welcome

Log all events since t=0
If new view is opened, it is sent all events.
For speed up it can first keep view server-side and then sent the whole thing at once
