Nice setup. I've got a similar one on a server:
Each daemon runs on it's own jail. Each jail is created from a cloned ZFS "base" jail filesystem, so it doesn't take any additional space (except each jail's installed packages), plus there are all the nice ZFS goodies (snapshots etc). There is one package-building jail. Every http request is served from a jail running varnish, which serves as a caching front-end to all the other http daemons in each jail.
