It is all in my pocket/belt clips! Most of the adaptors are really tiny and plug into each other (2+3+4+5, 6+7+8+9, 15+17+18+19+20+21+22+23).

p. WiFi to HDMI would be something like a Mirascreen/Chromecast dongle. Anything that supports AirPlay so that it will work with Apple devices. The Egoman DT302 uses the same chip as the Raspberry Pi (BCM2835) and has USB host, but is a bit long to fit inside the iPod. If I could find something similar with the dimensions of the Corewind WiFi G25 (50 x 30 mm) then that would be perfect.
