[maemo-developers] FM RDS data

I have been approached by a person interested in sending data from a sensor
via FM to a cellphone which would in term transmit this data to the
Internet.  I am interested in figuring out if this is something that could
be done with an N900.  With that, I have a few specific questions:

First, can anyone point me to information about how to programatically
receive RDS data?  I've read that the FM receive app is supposed to do that,
but I haven't managed to receive RDS data that way yet, and I don't have the
source code.

Second, does anyone have any idea what frequencies the FM receiver can tune
into?  The programs I've seen have focused on the traditional commercial FM
band, 88 Mhz to 106 Mhz.  Can the FM receiver tune in higher or lower
frequencies?  If so, what is the real frequency range of the FM Receiver.

Third, are there other data formats that can easily be sent and/or received
from the Nokia phone?  If so, can people point me to any of these other data

Any help you can provide would be greatly appreciated.
