[lime] How to propagate a 'server' name?

If I run a service on a node, is there a way to propagate a unique
hostname for that service, seperate from the node's hostname?

What about running the service on a static IP on a non-mesh node
(plugged into a LAN port) ?

I've observed that the hostname used in client's DHCP queries gets
propagated - is that what existing networks do for servers?

My community network isn't connected to the Internet, so there's no
central DNS to add names to.

Thanks in advance
