Comment 14 for bug 703815

I suggest using python backend, which will give exchange data via DBus with Vala indicator. CouchDB integration can also be moved to Vala code.

GWeather has a rather small location DB and only one weather provider - Weather.com.
So it is less powerful than the current solution - geonames.com DB + PyWAPI with Google, NOAA and Yahoo backends. Other backends can be implemented in PyWAPI - I guess, it would be much easier contributing in this project.
