Sounds good.
One thing I noticed from the blog is that it doesn't (yet)
support styling information. You should be able to easily carry this
along using a similar method to the PdfWord used by the current TextOutputDev.

No, because in an interactive application, no such thing
really exists. The closest you can come is the destructor for the
OutputDev. I've put such things there before.
Another option is a new method for your callers to use...
