I'm happy to see that you want to work on this.

Probably better solution is use ufs library to create maintain  
journal (we can use journaling as mount option then). This library  
have to be jbd compatible if we want to use it for ext3 log.

We have done(mjf@,pavel@,wrstunden@) and me some work on this area.
mjf@ have written ufs-trans library [1]. Which can be used to create  
filesystem transactions.

I 'm working on ext3fs [2]. For now I can read/find jbd journal  
superblock. But
problem is that I don't have enough informations about jbd journal  
and therefore I have to read linux jbd code which is little bit ugly :).

Yes if you want, you can contact me with jabber/icq and we can
