I am not that big in D-Bus programming, but I think that is how it
should work. The failed signal then can contain an error code or we
simply use the error method for it.

Another thing is that we might wanna have a method where we can request
a name from the cache and if not available we request it.

Besides this we also should keep the extended inquiry in mind. This can
deliver us the full name via an inquiry response or at least a short
name for a device. So what I see is we have four different types of
device names inside our system.

	- Full device names (up to 248 characters)
	- Short names or inquiry names (up to around 235 at max)
	- Cached names (in generell only up to 248 characters)
	- Alias names (no length requirement)

How do deal with them through a nice interface, because all of them can
be different.

Regards

Marcel
