Answer 1

You could try using SSDP. It's what UPnP devices use to discover each other. It's multicast on port 1900 and just uses really simple packets to send around IPs and service information.

Cling is a UPnP lib you can pull from. Note I'm not recommending you move to UPnP - just the discovery protocol used.
