"write a message to us" ??
Seems like a function an e-banking site offers and could support html one day.
Your other use case remains strong.

One thing that I like in the DOM exposure of the HTML flavour is that it prevents an amount of the threats related to parsing and that is good. In MathML (as in any xml fragment), the only dangers are, I believe:
- parsing time: related files inclusion (schema and dtd notably)
- image and/or style embedding
The first danger is eliminated if the fragment is exposed as a DOM fragment (provided the reference is removed of course).
The second danger is eliminated by the same techniques as those with HTML.
