Neo4j stores data to the filesystem, Google App Engine does not allow applications to write to the filesystem.
It could be possible to use Neo4j in read only mode with a pre-created uploaded graph, probably requiring some minor changes in Neo4j, but I have some doubts about the usefulness of this approach. As I've said before, the best way to get Neo4j onto GAE would be to reimplement the Neo4j Graph Database API on top of the AppEngine datastore. Using bigtable (i guess it is) for persistence and Googles memcached API for the cache. It would be an interesting project, especially the caching part, since that is shared between the AppEngine servers, but I have no idea what the performance numbers would be in the end.
