These things are on my wishlist as well. It seems like all things are going the way of XML, and people have been kicking around ideas of making LilyPond more XML friendly for a long time now (check out the mailing list discussions about a ly->musicxml converter). The issue is that LilyPond is a program cobbled together from many different contributors with different specialties and thus does not have a unified way of representing or channeling all graphical data (especially when it comes to getting these data to talk to each other). A big project of mine has been making \markups behave like grobs, but it may take me two years to get it all straightened away. I think that, in development, it's important to balance wishlist thinking (which is what I do with most of my patches) with expedients. Obviously too much of the latter leads to really kludgy ways of using code, but too much of the former means that nothing ever gets done.
