Using Bluetooth devices @initramfs

hi,

i am trying to get a file from a blootooth device during system boot.
my root-filesystem is encrypted and i would like to be able to get the 
encryption key from my mobile phone.
i have written a script, that is getting the key-file with obexftp. it is 
working as expected as long as i am running it from a fully started linux.
no i am trying to get it running in the initramfs and i am stuck.
the modules are loaded, hciconfig is showing me the proper device.
so far, so good, but:

as far as i understand bluez, i am in need of hcid running to communicate to 
my mobile phone. but trying to start hcid in the initramfs is a pain.
it seems to be in need of dbus.
i believe it goes very far beyond the scope of an initramfs to have dbus 
runnnig there.
just to give a simple example, dbus has user and group policies and is usually 
started as another user than root. this is all out of the context of an 
initramfs.

i got the dbus-daemon running in the initramfs after some tries, but starting 
the hcid still fails with connection errors (hcid is not getting response 
from dbus for whatever reason)

now i am stuck.

is there a way to communicate via obexftp to my mobile-phone without hcid?

or is there a way to start the hcid without dbus?

best regards
mog
