I wonder if it would be practical to use 2 open source phones as
sniffers, one to sniff the uplink and the other to sniff the downlink.
 If you could get them started then in principle they should be able
to hop along to follow it.  That would be an interesting project!  It
would be a very cheap way to do it if it's possible.
