I'm certain one can find ways to make this work but I'm also pretty  
certain that we'd see some "less-than-clean" implementations of the  
feature and the result will be additional client incompatibilities.

Let me add one problem to the list: I think Kontact already uses HTML  
markup (or was it RTF?) in the plain text fields. As far as I know one  
can use formatted notes within Kontact and I remember these were  
looking horrible in Horde :)

I'm really in favor of keeping to plain-text. Anything styled should  
simply go into the attachments.
