  Service discovery is pretty easy with UPnP as well when using GUPnP.
All you have to do is to create one object and listen to signals for
device/service (un)availability. Unfortunately, we don't have python
bindings but keeping in mind gupnp is mostly gobject-based, it
shouldn't be a challenge to implement.

  One important thing to keep in mind when comparing avahi/mDNS/etc
with UPnP is that UPnP is much more than addressing and discovery:
Zeroconf defines standards for the addressing and discovery of
services on a network but do no define any means for description[1],
control, event notification and presentation.

[1]  We all know how useful D-Bus introspection with d-feet is, the
usefulness of UPnP description combined with gupnp-universal-cp is
quite the same.
