RDS/RBDS FM receiver (external) for traffic conditions

A lot of my personal interest is in context-aware aps (particularly with
the embedded GPS) and (unfortunately) I spend a fair bit of time in my
car each day. It would be really nice to get traffic updates to the neo
as an enhancement to any mapping/navigation programs.
and *no*, this is not a request to change the hardware - there are
external modules that would work.
The one that looks most interesting to me is the Si4701 - available in
the US from mouser electronics for $35.

The interesting thing to me is that they supply source for both the
firmware and the GUI
unfortunately it looks to be linked to M$ c++ extensions. I got an
error on missing stdafx.h when I tried to compile the RDSData.cpp file
(which as near as I can tell comes from a M$ dev kit)
Would this be usable as reference to generate linux code
(copyright/licensing mavens among you)? is there any interest in this?
They claim it uses standard USBaudio for the sound and that they use the
HID spec for control interface (which doesn't make a ton of sense to me,
as it seems backwards, but I have not reviewed the spec).
This is also the FM chip used in the M$ Zune, but there doesn't appear
to have been a lot of progress made on the linux front there.
Interested to hear your thoughts on this.
