I notice in the list of mentoring organizations for Google Summer of Code 2009 there is no organization representing Ruby.
Last year, I had a student who was interested in debugging support in Ruby 1.9 but due to a snafu on the part of the Ruby Central administrator, Ruby lost the student altogether.
Earlier this year in the ruby-core mailing list, I mentioned the possibility getting another student to work on some core changes into YARV (the 1.9 VM), Kochi indicated he'd be interested in mentoring. Given this ideal situation, would it be possible to list such a project as part of Ruby Rails?
P.S. The "core" email address listed on http://socghop.appspot.com/org/show/google/gsoc2009/rails bounced email back to me saying there is no such account.
