LilyPond reads the cm TFM files to get spacing information for
texts. I don't see any other easy (and obvious to persons with non
standard TeXs) way to get to those files.
The solution is excellent, but the name of the directory is
unfortunate because `tfm' is a generic name in the TDS-tree. I
suggest to use `cmtfm' for what you currently call `tfm'.

Because I get approximately 20 e-mails per day about LilyPond. I want
the installation to work out without handholding from my part.

So? I still have to figure where in this large tree I need to
read/write files.
I suggest the following procedure *which will work only with a TDS
compliant tree*. For any other TeX tree layout, automatic
installation is impossible IMHO due to the non-standardized search
paths in kpathsea:
0.) Install the LilyPond files in /usr/local/share/lilypond as
usual. In the following, I call this directory $LILYPOND. Only
links are created.
1.) Search whether e.g. feta11.tex exists (using kpsewhich). If
yes, abort the installation so that the people can remove an
older lilypond package.
2.) Get the whole $TEXMF path with
kpsewhich --expand-path=\$TEXMF
3.) Parse the above directory path until you've found the first
writeable/readable directory. In the following, I call this
directory $MYTEXMF.
4.) Create links (if necessary, create the parent directories):
ln -s $LILYPOND/tex $MYTEXMF/tex/lilypond
ln -s $LILYPOND/ps $MYTEXMF/dvips/lilypond
ln -s $LILYPOND/afm $MYTEXMF/fonts/afm/lilypond
ln -s $LILYPOND/tfm $MYTEXMF/fonts/tfm/public/lilypond
ln -s $LILYPOND/mf $MYTEXMF/fonts/source/public/lilypond
5.) Run either texhash or mktexlsr.
