Tcl/Tk Community handles enhancement to Tcl/Tk code base with TIPs (Tcl Improvement Proposals - for details see http://tcl.tk/cgi-bin/tct/tip/) and SourceForge.net Tracker for Bugs/Feature requests/Patches - see http://sourceforge.net/tracker/?group_id=10894). There is also plenty ideas floating in this Tcler's Wiki so you are encouraged to browse these links to see what is currently needed. 

You will probably find a mentor for any reasonably defined project inspired by browsing mentioned resources. But this particular page is for mentors to publish outlines for proposed projects. That way it would be simpler for students to discuss, choose and apply with Tcl as mentoring organization. It would be best if goal of the Google Code of Summer 2007 student project will be finally described in TIP like fashion. But lets start with what we've got now:


   * multiplatform embeddable multithreaded application web server in Tcl
modular, supporting http/1.1 mechanism

   * full bindings in Tcl for DDEML (Dynamic Data Exchange Management Library - MS Windows IPC used in many SCADAs)
scada application, dde servers, serial communication facilities build into tcl

   * Tcl/tk framework for building database/form-based application a'la Borland Delphi
compose sample application form available components, integrating it and showing how to use and glue them together to accomplished database application in Tcl

   * enhancement to starkit/starpack deployment for multithreaded application
