It's a public mailing list. On-topic conversation is implicitly invited. :)

That's a _very_ interesting idea. I don't know of anything that does it 
now, but there very well might be some XML technologies for doing it (I'd 
hesitate to apply it to non-XHTML HTML, personally). Would be neat to code 
a diff driver for it...

You should be able to do it, using external code of course, as long as you 
can retrieve two revisions.

Well, shucks. :) But maybe you'll have time in the future, or this will 
spark someone else's interest.

Yeah, sounds like we might want to have a Chora_Diff class with pluggable 
drivers...
