No support for the on() function?

[TTimo]

So the on() functionality in Firebase is really interesting for my use case:
https://www.firebase.com/docs/javascript/firebase/on.html

Am I correct that this isn't supported with the python-firebase module? The REST API doesn't seem to have support for it, and python-firebase is a wrapper .. therefore ..

I'm just looking for confirmation or if you have some alternative suggestions.
