The main problem why reiserfsck does not process similar to other fscks is that reiserfs (as well as reiser4) moves data on filesystem modifications so that even files which were not modified recently change their locations. Online reiserXck should be probably implemented as kernel thread. Or be able to block filesystem updates, or I do not know what. So, in short, reiserXck for r/w mounted filesystem can not be implemened as plain user land tool,imho. Also imho, currently the problem is that it is not very clear how to do it.
