SharpEye2 works very well for me, too (if your sheet music is clean and
aligned on
the scanner grid...) - and it can export to MusicXML, which you can turn
into Lilypond with xml2ly, http://www.nongnu.org/xml2ly

You may want to look at Gamera: I discovered it some time ago, but was
never able to have it working because of memory leak while compiling
version 1.0. I've just gone ot the website -
http://dkc.mse.jhu.edu/gamera/ - and seen version 2.0 has been released.
Version 1.0 was GPL, but I cannot find any licensing information for 2.0

Cheers,
Guido

ps.: I sent this message to Graham only some hours ago by mistake. In
the meanwhile I got Gamera 2.0 compiled: I took about 60MB of memory...
