This is the place for ideas regarding GSOC 2014. They have been sorted by difficulty:

Simple means that choosing one idea won't be enough, and an applicant needs to tackle at least three of those to be considered.
In the category Medium at least two ideas must become part of a potential GSOC project.
Picking up an idea from the High category could be enough to qualify, although it may be necessary to add an idea from Simple.
Demanding will be definitively enough for a single project, but applicants need to prove their skills before they can be considered.
Unknown is a category which will take some investigation to decide its difficulty, and also means that it can be reassigned once this is determined.
