GSoC project idea: HFS Plus journal

Hi, I see some of you are talking about GSoC participation. I'm also thinking of it. I have MacBookPro booting both MacOSX and Linux. Now Linux can write the filesystem safely only when HFS Plus journal is off. My life would be more better if Linux have complete HFS Plus filesystem read/write support. So I'm thinking of implementing HFS Plus Journal support on Linux. I've searched and found a technote about HFS Plus format describe its Journal [1]. How do you think about it?
