In the last years,
<http://www.gnu.org/software/soc-projects/ideas-2013.html#hurd>, etc.,
we'd just place a pointer to our project_ideas page onto the GNU ideas
page, so I suggest to do that again. Separating out just a few project
ideas does not make too much sense to me -- what may make sense is to add
a high-level overview of the projects to the GNU page, like a list of
keywords: »hurd, kernel, distributed, file system, language bindings«,
etc.
Is your intention to participate under GNUs umbrella or did you apply as
a mentoring organization?
