In Bluetooth++, I showed the cups bluetooth backend enhancements. Marcel is currenly reviewing those, and should merge the code upstream next week. In the meantime, the code is available in bluez-utils-3.11-2.f8 in rawhide.
I've also been working on James' gnome-vfs-obexftp code. While the old code needed you to make hcid launch with the -x option to enable the experimental features (in this case the now-defunct RFCOMM service). Marcel told me it should be using RFCOMM sockets directly, and we now have a version of gnome-vfs-obexftp that works without any tinkering, and is also more reliable, and quicker.
It's also available in the repos for Fedora Core 6, Fedora 7 and rawhide under the name gnome-vfs2-obexftp.
