According to
http://code.google.com/soc/
there is not much time left until applications are accepted:
Welcome to the home page for the Google Summer of Code program!
.
.
.
We will begin accepting applications from mentoring organizations on
March 9, 2009. In the interim, you can peruse our 2009Frequently Asked
Questions page. Please subscribe to the Google Open Source Blog or the
Google Summer of Code Discussion Group to keep abreast of the latest
announcements.
Therefore I have created the following wiki page:
http://wiki.gnustep.org/index.php/Summer_Of_Code_2009
and hope now that this mail results in a fruitful discussion and
volunteers who take care for GNUstep at Google Summer of Code'2009
Thanks,
Lars
