I connect to pisound from various devices on my network from windows, mac, ipad, iphone other pis and always struggle to find the IP address for vnc or webgui access.
Sometimes I was unsure if my pi had crashed or my network had rebooted with a new ip address so i would get out a monitor keyboard to hook it all up so see what was happening.
I had a couple of Sparkfun Microviews laying around and put together some code that runs persistently on the pisound pi to display the current ip address.
I can now plug in the USB Microview and up pops the IP address.
The code can be downloaded from github
