hosted service within one month. email apps VERY high on our to do list, been watching freedombox for a while, we'll reach out to them after initial release.
Since you mention Freedombox – did you also check out ownCloud as well as the unhosted movement, with the remoteStorage protocol? There is a proof-of-concept social network build on unhosted: http://friendsunhosted.com
Do you have an IRC channel? Feel free to also join our channel at #unhosted. :)
