that's the same problem with the WMS provider, there isn't a way to
get the GetMapUrl... and parsing the metadata string is not a good
option :)

I think all the providers should have a method to get useful props,
so plugins can get those kind of provider-specific information,
something like:
QVariant QgsDataProvider::getProperty(QString)

Any reason to not doing it?
