Michael's little experiment with setting up a SqueezeServer using FreeNAS + SlimNAS got me thinking: what other FreeNAS extensions are out there? Officially, there are only two listed extensions - SlimNAS enabling a SqueezeServer and CCXStream enabling Xbox streaming. Some Googling found mt-daapd for my version of FreeNAS (I'm still running the 0.68 series, so no built-in DAAP server for me yet). zsole mentioned something about an anti-virus plugin and a Bittorrent client (neither of which I've been able to find, I must admit). Other than that... what else is out there?
