We've published a project ideas list for GSoC here: http://julialang.org/gsoc/2014/
We'd like our ideas page to be as healthy and diverse as possible, so please do make your suggestions. Projects can include things like new packages, specific language/package features, or something more experimental; really, there's scope for any kind of coding project here, but those which fit roughly three months of work and have a clear, tangible benefit are best. If you maintain or use a package which is missing key features, now would be a great time to ask for them! You're welcome to add project descriptions via github, but if you want to suggest something more informally you can do so here - I'll continue to write up as many as I can. Thanks, Mike
