If it's easy to get to I could also use it from Formulator, which,
though I don't guarantee perfect security, at least has a design which
makes it far less easy to fool than the Zope marshalling :foo 
thing (which you can fool just by writing your own HTML form).
All you'd need is add a HTMLField to the system which has the
right knobs to set what you exactly want to allow in entered HTML -- 
that's also a far better user interface than thinking up yet another
marshalling :html:foo:bar strategy..

Anyway, just a module that I can import from Python that exposes the
functionality would already be worth a lot having in the core; I'm
loath to introducing dependencies on non-core stuff in Formulator, as it's
aiming to be a very fundamental product that just should work out of the
box. The only non-core dependency right now in on TALES, but it still
works without it; you can also use Core Session Tracking in a simple
way. Once Zope 2.5 is out I plan to start depending on sessions and TALES
a lot more though, as they have those in the core.
