Figuring out the IP address is easy at home , I can look at my routers home page and see the pi.
I'd like to take the pi into work, where I have no means of telling what hostname or IP address the headless pi is given by dhcp.
It occured to me that there might be some cool ways of the pi communicating with me on boot :
1) mail: I guess it could smtp me the IP address in the bootup. I'd need to hard code the relay server but it could work when at work ?
2) Sound : I've not looked into this but wonder if the Pi could announce its IP address via the audio out. Perhaps there is a speech synth that could tell me the IP address during boot. This would be very cool ("Hello Dave, my name is pi and my IP address is ........")
3) LED's

of course I could just plug in a Composite video or HDMI monitor, but that would be far too easy
