Hi Matt
Thanks for all your help.
I want my application to run standalone, with as few dependencies on
external services as possible.
Installing extra system services is a no-no because it increases the
likelihood of a customer accidentally breaking the configuration.
Bummer. I'm going to have to implement my own protocol to do this.
I know it won't scale as well as SLP, but I'm happy to trade off some
extra network traffic for increased application reliability.
Regards, Noel.
