We are very interested in SVG output, and we're working on it, but  
with only very limited resources I'm afraid. The reason we're  
interested is that we see it as an excellent vehicle for enabling  
Lilypond to be used as a typesetting engine in database queries.  
We're wanting to produce excellent quality scores automatically and  
typeset additional information which arises as the result of, for  
example, performance information stored in a database.

Stuart Pullinger made a quick hack of the scheme and there's a brief  
demo of what might be done here:

Not much yet, but much much better than nothing. We also had font  
issues, so the SVG gets converted to PNG server-side. Stuart's wiki  
page: http://markov.music.gla.ac.uk/cmt-wiki/StuartPullinger

I can't offer a bounty per se, but if any UK national with a 1st  
class or upper second in a numerate discipline seriously wants to  
work on this for three or four years, we might be able to fund a PhD  
studentship (£12600p.a. tax free if memory serves, no council tax to  
pay). email me.

Perhaps someone should copy this to the dev list?
