Just jotting this down really. You need Lightblue installed, which also requires pybluez (hence bluez) and also openobex installed. OK, no further ado:

>>> from lightblue import *
>>>
>>> finddevices()
[('00:11:9F:C3:7E:A7', u'Nokia 6630', 5243404)]
>>> services = findservices("00:11:9F:C3:7E:A7")
>>> services
[('00:11:9F:C3:7E:A7', None, u'SDP Server'),
 ('00:11:9F:C3:7E:A7', 1, u'Hands-Free Audio Gateway'),
 ('00:11:9F:C3:7E:A7', 2, u'Headset Audio Gateway'),
 ('00:11:9F:C3:7E:A7', 10, u'OBEX File Transfer'),
 ('00:11:9F:C3:7E:A7', 11, u'SyncMLClient'),
 ('00:11:9F:C3:7E:A7', 12, u'Nokia OBEX PC Suite Services'),
 ('00:11:9F:C3:7E:A7', 9, u'OBEX Object Push'),
 ('00:11:9F:C3:7E:A7', 3, u'Dial-Up Networking'),
 ('00:11:9F:C3:7E:A7', 15, u'Imaging')]
>>>
>>> D = [ (x,y,z) for x,y,z in services if "obex" in z.lower() and "push" in z.lower()]
>>> D
[('00:11:9F:C3:7E:A7', 9, u'OBEX Object Push')]
>>> (device, channel, description) = D[0]
>>> obex.sendfile(device, channel, "/media/usbdisk/Kamaelia/cat-trans.png")
