Thanks Felipe - it does more than I expected :-)
What are the thoughts on editing capabilities?
For example, will there eventually be a control based on this work in the platform which supplements or becomes the implementation for the HTMLEditor?

The current implementation has two different approaches for finding break opportunities in the text.
For complex text (thai, etc) it uses java.text.BreakIterator, for English/Latin it uses simpler implementation (which is faster).
Bugs like start lines with spaces or breaking IP address (or email address, see http://javafx-jira.kenai.com/browse/RT-24735) will be fixed.

Other than those of us internally who have argued for / against the Attributed String style vs. the DOM style, most people probably won't get the subtlety, having missed the context.
