Gnome1394 allows one to access the IEEE 1394 bus (FireWire, iLink) in an easy way from Gnome. It needs the IEEE1394 kernel patch and the library for raw access to the bus. All can be found on the project's homepage. Note that at the current stage access is very limited and only simple bus transactions are possible. It doesn't do useful things at the moment, target audience are developers and people who want to see that Linux is starting to support IEEE1394.
