The "/.reply_to" will be a lease. Registering application has to renew
it's subscription.

Right now, I propose to move on. I will implement the draft of
"oscplanet" (http://rubyk.org/en/article162.html), build the library
and then everyone interested can test, experiment and propose better
ways. There is nothing carved in stone right now and zeroconf might
play a bigger role in the subscription/lease thing that I might not be
aware of right now.
