I guess you could do this by extending GVM, or using some callout in
ivman ;-)

I guess HAL is most suited for the task: after all it's HAL that creates
the messages on the DBUS system bus.

You can use libhal (I dont know if there are python bindings for this?),
or listen on the DBUS system bus directly.

I don't know about HAL<->python, but if you'd listen directly on the
DBUS system bus, check out Ross' IBM article [1], there's some Python
code in there, and the Python samples in the DBUS sources.
