Walking in Tokyo with iPod

I have uploaded the first Walkin' in Tokyo Project Walk Guide to display on an iPod with Notes function. This document you can download here contains right now only two walk courses indications. The walk starts from Hotel Grand Palace near Kudanshita. If you are staying or living in the area - including Hotel Metropolitan Edmont - and you are an iPod user, I would be delighted that you test the courses that a really nice and send me feedback on the usability of this tiny trial. Also coming with this iPod document is a hand drawn map for the first walk that goes up to the Hotel New Otani via Yasukuni shrine and Sotobori outer moat green walking trail. I will create and add maps for further walks when time allows. Again, feedback is very welcome as usual.
