Learning my way around UPnP and DLNA.
Completed steps:
step 1: UDP UPnP discovery
step 2: getting info about the devices found on the net
step 3: getting info about the services found on each device
Coming up next:
step 4: getting list of commands the device services support, maybe calling some
step 5: being able to push an image or video to a render device would be nice
