Hi all: I found this post randomly googling, and I'm happy to see that someone noticed the Lobotomy Project ;-). I am the founder (and, at the moment, the only developer) of the project, and I'd like to evidence that Hyppocampus and the others of the Lobotomy suite aren't defunct, just proceed really slowly due the fact I can dedicate them only some hour per week.
Currently there is a page,
http://lobotomy.sf.net , where all news and documents are released in a bad but understandable English (I'm italian ;-P ). I'm working on the 0.2 release of Hyppocampus and Synapse, which are very unstable and extremely experimental but permits to interact in some manners with the relational filesystem. In the above linked URL you find also some screenshot of the current state of the filemanager.
I hope someone, reading this post, have interest about this ambitious work, and decide to collaborate as developer, tester or just advancing some suggestion.
