After developing VMC for Vodafone, we started an internal prototype to
DBusificate the core and integrate it with NM. Development got stalled
for a while but here we are :)

Small demo:
[huno satellite:~] $ dbus-send --type=method_call --print-reply
--dest=es.warp.VMC / es.warp.VMC.GetProtocolInstance
string:/org/freedesktop/Hal/devices/usb_device_12d1_1003_noserial
method return sender=:1.99 -> dest=:1.100 reply_serial=2
  object path "/org/freedesktop/Hal/devices/usb_device_12d1_1003_noserial"
[huno satellite:~] $ dbus-send --type=method_call --print-reply
--dest=es.warp.VMC
/org/freedesktop/Hal/devices/usb_device_12d1_1003_noserial
es.warp.VMC.PIN.Send string:0000
method return sender=:1.99 -> dest=:1.103 reply_serial=2
  string "OK"
[huno satellite:~] $ dbus-send --type=method_call --print-reply
--dest=es.warp.VMC
/org/freedesktop/Hal/devices/usb_device_12d1_1003_noserial
es.warp.VMC.Network.GetSignalLevel
method return sender=:1.99 -> dest=:1.105 reply_serial=2
  int32 28
[huno satellite:~] $ dbus-send --type=method_call --print-reply
--dest=es.warp.VMC
/org/freedesktop/Hal/devices/usb_device_12d1_1003_noserial
org.freedesktop.DBus.Introspectable.Introspect > vmc-core.xml

Attached you can find the current API

We've been working on this as an internal R&D project till the
possible future integration with NM, but we'd be certainly happy to
have you (and anyone else) tinkering. I'll prepare a trac for next
week, I'll keep you posted
