fonts and lisense

[Guido Amoruso]

Hi,

I've been reading some discussion on the Xemo mailing-list
(http://www.xemo.org) about fonts. They are interested in creating
and/or modifying free music fonts, in order to use them in their open
source platform: I don't know details about that, but they'd like to
make it possible to build both proprietary and free applications around
it.

The questions are:

1. which is Lilypond font lisense? I looked for the lisense in the *.mf
files, but did't found it: is it GPL, LGPL or another one?
2. in the last months I've seen interest in music [free] fonts is
increasing: maybe it would be most safe to add some lisensig terms in
Lilypond fonts' sources.
3. do you think it is possible to use GPL fonts in a proprietary
product? I mean, any modification to the fonts should be GPLed, but
perhaps that would not regard the whole application.

Cheers,
Guido
