[B.A.T.M.A.N.] Interested in contributing

Hello folks,

I came across the list of improvements and ideas to work on B.A.T.M.A.N-Adv from Gsoc2013 Ideas here https://wiki.freifunk.net/Ideas_GSoC_2013 I am interested to work on implementing a proposed solution to any of the mentioned problem. The wiki has a list of problems but, there is no description about the current status of each problem listed (whether they have been already implemented or still looking for contributions?).

If there are any other problems apart from the above list, I would also like to know those to see if I can contribute.
