Spent two days solid working on GNOME Bluetooth this week, great to get the hacking time. Have reimplemented the libraries extensively, excising the redundant and failure-prone Bonobo component, and adding in asynchronous device discovery and Python bindings.
All in all, things are heading in the right direction to give GNOME users a decent set of Bluetooth tools. Hopefully I'll be able to get a point release out soon, as a lot has changed.
