Something that came up on the list recently was adding support for pipelined commits via ra_serf. Would this make a good GSOC project? It seems like the kind of "engineering" challenge that might appeal to a student. I have no idea if it is too big or small for GSOC. For example, I have no idea if this is something that can be done with just changes to our client or if it also requires modifying mod_dav_svn.
