Since it's using FUSE, it would be nice if it had lazy initial syncing. I.e. on empty filesystem slave it would serve/sync accessed files even if they are not synced yet. That's at least until full sync is completed. Millions of files or GB's of data can take long time for initial sync. And lazy sync would allow to start serving clients with no delay.
