No, they have restarted activies some weeks ago. At present there is
some discussion about fonts: even if this does not reguards Lilypond
directly,
it can be useful to have more free music fonts (as far as different
applications
can use them in different ways).
About the future of Xemo, I hope it will gain some real achievement: I
don't know whether it will, but such effort can give useful results as
well.

Ok.

I have to ask you one futher piece of information: which are exactly
sources? I mean: I think they are the metafont files (.mf) and the .tfm,
but I don't know much about that.
