Convert Visio Shape text to RTF (or HTML)

[Nikolay]

How do I convert Visio shape text to/from RTF (or HTML)?

From Graham's book:

Currently, there is obstacle to this idea: The Visio object model does not have a way to exchange a RTF version of shape's text. Actually, that's not quite true - Visio can copy and paste RTF via the clipboard. However, disrupting the clipboard in order to exchange data between Visio and your solution is probably not an acceptable programming strategy.

The current workaround is a long one: Create a component that understands how to translate between RTF and ShapeSheet Character/Paragraph section, at least to the degree of formatting complexity that your solution offers to users.

So, probably someone has already created such a component and wants to share it with Visio community? 

Or, probably with Visio 2010 object model does have a way to exchange in RTF/HTML?

Thanks in advance
