Dear Yitzchak,

On the AMEEL (A Middle Eastern Electronic Library) project here at Yale we are using javascript rendered tree to expose a fedora repository of journals, both as a simple browse of the title,volume,issue,pages hierarchy expressed in rels-ext isMemberOf relations and to display the results of search (a little more intensive in CPU and implementation).  If interested I can send you source code and possibly the test server url.

Best,
Eric
