> I'm afraid you're right, although I still can't see clearly how to do that in the way you suggest. For instance, how do I get the range associated to the full text in a text entry so I can truly know the offset for a given position, even if that text is internally represented by different text nodes?

Take a look at the static methods in TextIterator:
    static int rangeLength(const Range*, bool spacesForReplacedElements = false);
    static PassRefPtr<Range> rangeFromLocationAndLength(Element* scope, int rangeLocation, int rangeLength, bool spacesForReplacedElements = false);
    static PassRefPtr<Range> subrange(Range* entireRange, int characterOffset, int characterCount);
Examples of their use can be found in various places in the editing code. Take a look at IndentOutdentCommand.cpp for an example of use of rangeFromLocationAndLength.
CompositeEditCommand.cpp has examples of use of rangeLenght, that should be fairly close to what you need.
