The private beta program for the open font commissioned for Ubuntu has now been launched. With a webapp to help gather relevant feedback (submitted LP #602933 for better font detection).
The precise details of the DVCS tree holding the various font source formats and the licensing are still to be decided and revealed. Hopefully Kenneth (along with his design team @ Canonical) is looking into my recommendations from discussions at the last LGM and from follow-up emails on open font release and maintainership best practises.
Still waiting for more detailed feedback from you Kenneth...
