Copy/paste in Pivot isn't terribly difficult to work with, and it is actually already enabled for TextArea, at least for plain text. The problem is that text is always pasted as a paragraph. Sometimes you want this, but sometimes you want it to be pasted as a span. I'm not sure what the logic should be for detecting this case, but now that I think about it, it may not be as difficult as I thought. Maybe we can paste it as a paragraph when it has a trailing CR, but otherwise paste it as a span.
Re: maintaining styles - I'm not terribly concerned about maintaining styles embedded in other formats such as RTF. As you noted, that would be a pretty tall order, especially cross-platform. However, if we put Pivot-formatted text on the clipboard (either instances of the text DOM classes, or XML containing a serialized form of it), pasting styles should be a non-issue. So copy/pasting formatted styles within a Pivot app would still work.
