As I began really using Emacs about a year ago, I got the idea that the Emacs code base could actually be a foundation for a computer science curriculum - The Emacs code base touches on scripting, functional programming, application programming, systems programming in C, real-time problems, usability, cross-platform development, etc. etc.

An alliance with Racket would be an interesting option from the standpoint of language communities.

     - The community's core is [ relatively ] vibrant.

     - The community has more than a passing interest in 
       developing development tools.

     - The community is exceptionally stable because
       its members are often linked to academia.

     - It copes with endless September really well.

     - Its vision of open resources overlaps GNU
       somewhat.

     - Programming language problems are right up
       the Racket community's alley.
