Hi Cristina -- This sounds like it would be very interesting material for the chapter, thanks.
But it can be totally up to you to decide how much of it you'd like to contribute.
Whatever you feel comfortable with is fine.
In fact since the Roadmap is intendend to be a living document, in the future
when your paper (or papers!) is published, you can add in some more results
at that time, if you want.
So feel free to put together some text about this topic!

I have read the outline that you sent out and I am most interested in the TNO part. I have been working on a paper in which I demonstrate the limitations of the current TNO taxonomy. I show that each taxon has a large degeneracy when it comes to surface composition. The analysis was done by means of a large database of models (~20k) with a variety of compositions. The main reason for the degeneracy is due (I believe) to the choice of filters that were available for the taxonomy and the lack of albedo measurements for a still large number of objects.
I would be happy to provide more information if you think that it would help in the writing of the document, however, since this is ongoing research that I have just proposed to NSF and for which I am writing the first paper now, I am a little reluctant to leave it out in the open for everyone to see. What do you think/advise?

Hi Josh -- Good point, I'll add that bullet in to the outline.
To all: any takers on text writing?
