mod_dav_fs already has this walking code, with callbacks. It has a notion of postfix walking so that a recursive delete can be performed.
Of course, there is some DAV-related crap in there, too :-) But take a look at modules/dav/fs/repos.c for the "walk" stuff, and its related context structure. One of the questions would be how to arrange the callbacks such that a client can "telescope" paths themselves. For example, if you're copying things, you need to telescope source and dest paths. mod_dav_fs also has to telescope a URI during the walk.
