This looks good. I think it's a good idea for you and the other GSoC candidate which is applying for the same project to work together. If you both are accepted by Google of course.
This way some collaboration can occur which is how we generally work here at Directory and Apache at large. Really this is the most important part of writing good code and being successful.
Hello, i wrote an application to directory project in Gsoc2009 site, public part is here http://wiki.apache.org/general/KirillKosinov/GSoC2009/directory-proxy.
May be you have some suggestions about proposal, or advices how to write applications next year (if it is to bad).
