[avahi] browsing without event loop ?

My guess is that it's because it's cumbersome.

Sometimes, you'd like to write something like:

  for machine in services(type=_workstation._tcp)
  do
    shutdown $machine
  done

Using the call-back API makes it hard to express such simple things.

FWIW, I'm planning to add a "threaded" API to Guile-Avahi, whereby the
event loop would be run in a separate thread.  User threads would send
requests such as "list all services of a given type" to the
event-processing thread and would block until the event-processing
thread is done (e.g., until "ALL_FOR_NOW" or an error is caught).

Thanks,
Ludovic.
