I'm thinking that an application that allows writing AND drawing to
the kids' heath content would be cool.
Gecko already goes a long way towards that goal e.g.:
(this is a mashup of samples from [1] embedded in an xhtml document)

Must still figure out how to do that in an editable nsIDOMWindow
though, dynamic stuff seems to be turned off in editing mode. Maybe it
would work making only parts of the document editable and have the
drawing in a non-editable layer above.

And yes, I'd much favour just using gecko as rendering engine. Text
handling is very speedy, graphics unfortunately not (yet?).
