On the technology side, an inital set of hardware, networking, OS and apps exists. Kind of.
The DreamPlug forms the base layer of hardware and networking. Globalscale built this as a complete hardware and software package, but it has multiple issues.
Debian is the OS controlling the Dreamplug.
An initial collection of Software to build on - the off-the-shelf, ready-to-wear stuff - is listed in the wiki.
The obstacles, such as the speed of tor, information leaked from the TLS protocol and chicken-and-egg problems with trust, are also discussed on the discussion mailing list.
where to find the latest news
The most up-to-date discussions happen on the mailing lists. A full list of is on the http://wiki.debian.org/FreedomBox homepage.
where else to look for progress updates
All the places where announcements may appear are listed in the FBX discuss page.
A (very high level) roadmap lists the typical project steps - requirements, design, implementation an so on - but as the FBX project is going in a new direction, there will be plenty of looping back to repeat steps.
