Beyond creating a manual listing which is easy to read frmom a web page
but gets out of date pretty quickly, maybe we could consider a dynamic
advertisement mechanism like ZeroConf:

This would be analogous to what RIP is doing for the AMPR routes but for
services. Remote machines would then advertise their available services
via Avahi for Linux, Bonjour for OSX, etc. There is also SSDP for
WIndows that does a similar function which is supported by many SOHO
routers as well.
