While you're holding back a few surprises, this little add-on for the iPod has been released by Griffin Technology - the guys who make that really cool Volume Knob with the blue LEDs , the Griffin PowerMate.

Follow the link for the info in the iTrip FM transmitter module for the iPod.

Whats really cool about this design is that its self-powered from the iPod [via the headphone socket] and you select the FM frequency to broadcast by "playing" certain files to the unit - very,very clever. It also "powers down" the FM transmitter after 30 seconds of silence - e.g. when you stop playing.

This could be one cool add-on for the "Pearl" - of course, you may already be planning such capabilities...

... If not, then maybe its not too late to look at something like this as a after market add-on.
